Bug 169115

Sorry... The kernel panic right after HW inicialization (inserting of modules)
even BIOS has been updated (and with no mem= line passed to the kernel) with
this message:

Kernel panic - not syncing: PCI-DMA: high address but no IOMMU.

So with no mem= or old BIOS the kernel panic just before "audit(...):
initialized". With latest BIOS the kernel boots but panic when modules are
loaded (probably forcedeth module for NIC).

With latest BIOS and mem=4094M the system boots and seems to be able to run.

I tryed the latest kernel from RHEL4 Beta channel
(kernel-smp-2.6.9-17.EL.x86_64.rpm) with no luck. Still kernel panic without
mem=4094M parameter.

The system is still unable to handle more than 4GB RAM.

The system has troubles with clock instability too, see bug #168255.

I have the same problem on supermicro h8dce motherboard.  There seems to be a
workaround for the latest bios. It has an OS options of "linux kernel 2.6.9". No
other settings seems to help.  With this set, I was able to load the OS and run
the OS as long as I do not choose the SMP kernel (I just kernel panic).  So is
this just a 2.6.9 codebase problem?

With the 2.6.9-22ELsmp I am able to run just fine.

With the 2.6.9-22ELsmp I am able to run just fine.

Sorry for the repeat, got a "Mid Air Colision" message for bugzilla and told it
to submit anyway.  Here is where I got the kernel that worked for me.

http://people.redhat.com/~jbaron/rhel4/

Kernel .22 did not helped here (ASUS A8N-E, Athlon 64 X2 Dual Core 4400+ and 4GB
of RAM), I still have to pass to kernel option mem=4094M. Without his I've got:

PCI-DMA: More than 4GB og RAM and no IOMMU
PCI-DMA: 32bit PCI IO may mulfunction.<6>PCI-DMA:Disabling IOMMU
...
Kernel panic - not syncing:PCI-DMA: high address but no IOMMU

Can you send us a serial console dump for this issue?  I'd like to see a little
more context.

Ok, I double checked my bios and even with the new kernel, if the bios is not
set to "Boot OS Linux Kernel 2.6.9"   I still kernel panic:

Initializing hardware...  storage network audio done[  OK  ]
Configuring kernel parameters:  [  OK  ]
Kernel panic - not syncing: PCI-DMA: high address but no IOMMU.

I see update 2 with kernel version .22 was released.  Has anyone tried it to see
if a fix is in the released kernel?

Got to try this today.  On the system with the option to specify the "Linux
Kernel OS 2.6.9", if I have this option set, it boots and loads.  If I have the
option set to other OS it dies.  

This is with the WS4U2 released yesterday.

Here is what I get on the console(this is with WS4 U2- released):

Starting udev:  [  OK  ]
Initializing hardware...  storage network audio done[  OK  ]
Configuring kernel parameters:  [  OK  ]
Kernel panic - not syncing: PCI-DMA: high address but no IOMMU.

Can you hook up a serial line to the system and capture all of the console
messages from boot to crash?  You would have to add flags such as
"console=ttyS0,115200 console=tty0" to the boot command line.  We can't help
until we know more about your system.

Boot to crash

Any word on this?

I submitted the information you asked for almost 3 weeks ago.  Any word on a fix
or help on this?  I saw a new kernel was released today that fixed other
problems I have had, but no mention of this.

Thanks

-Brett

Until U3 there will be no fixes than security fixes (or really serious bugfixes
for big RH customers). But yes - testing kernels are welcome here too...

This problems dates back before U2 was released.  Why no fix then?  Why no
progress on a fix before U3?  

It turns out to be a PCI config space access issue.  A temporary workaround is
to specify the boot parameter "pci=nommconf".  I have a patch that will
auto-detect this platform and specify the correct type of PCI config space access.

I'm confirming, that workaround from the comment #19 works here. Is there a
possibility to test this patch (I'm able to compile own kernel)?

Oops. The machine boots but hangs as soon as higher load come :-( Repeated three
times there.

What kind of load are you running?  We have a similar configuration here at Red
Hat (which I used to come up with the workaround in Comment #19), and I've not
heard any reports of mysterious hangs...

Hang has been seen at ASUS A8N-E with AMD Athlon 64 X2 Dual Core Processor 4400+
and 4GB of RAM. I have no dirrect access to this machine so if you need more
info I have to talk with the responsible person. But I would like to provide as
much information as possible.

See http://lkml.org/lkml/2005/11/6/54 for some ideas -- try booting with
"iommu=soft swiotlb=65536".  This bug may be a duplicate of bug #166437 which
was fixed in 2.6.13-based kernels but reappeared in 2.6.14-based kernels.

While "iommu=soft swiotlb=65536" works, it may be better to use "pci=nommconf"
as recommended by Andi Kleen at http://bugzilla.kernel.org/show_bug.cgi?id=5343
-- the problem he reports is that the MCFG table provided by ACPI BIOS is broken
and needs a fix.  He is developing a workaround.

The MCFG table describes the memory mapped PCI configuration space, which is
required for the MMCONF form of access to devices on the PCI-Express bus
(otherwise, one must address them through BIOS or directly).

Anyway, using the boot line option "pci=nommconf" works for me, and I'll use
this until Andi's workaround arrives.

Hmmm... Comment #18 and Comment #19 seem to be lifted straight from Bug 166437.
 Can you tell me if either of the workarounds ("iommu=soft swiotlb=65536" or
"pci=nommconf") works for you and prevents the hang from happening?

I am facing the same problem, I'm running an Athlon X2 3800 on a Biostar NF4
mobo with 4GB RAM and an Adaptec 29320A Ultra320 SCSI adapter. I've been facing
instability for 3 months now. I started with FC3 and the 2.6.12 kernel, this was
very unstable, because there was a bug with the SCSI adapter and memory
addressing. 2.6.13 and later solved this problem, but the system still locks up
at random times. My server usually locks up within 1-50 hours, uptime has never
been more than roughly 2 days. I've upgraded to FC5 Test 1 last week but even
the latest 2.6.15 kernel didn't solve this.
I've brought the memory usage down by using "mem=3500M" (been using that option
for 2 months now with various kernels), but the system is still unstable. I just
wanted to eliminate the 4GB+ problem, but apparently it's still unstable. It
always boots, but it just locks up at random. I'm using "pci=nommconf" on top of
"mem=3500M" now, but it crashed after about 8 hours of uptime. I think this is
not working either, so if it crashes one more time I'll try "iommu=soft
swiotlb=65536" and keep you updated. I've posted dmesg below:

For RHEL4 users, can you please provide feedback as requested by
the developer on comment#27?

For Fodera Core users, can you please file a seperate bug, so that
we can track it with FC?  Mostly because the kernel base are different
between RHEL4 and FC5.

I have the same problem with RHELU2 on a similar H/W with more than 4GB memory,
the workaround "pci=nommconf" seems resolve this.

Another workaround i observed is to disable "ACPI MCFG Table" in BIOS 
(i.e if there is an option in BIOS)

Created attachment 124675 [details]
dmesg output

We're also experiencing this issue with a Fujitsu-Siemens Celsius V830
(Gigabyte dual Opteron motherboard).  A regular boot panics with Kernel panic:
PCI-DMA: high address but no IOMMU.

The attached dmesg is the output when using the pci=nommconf boot option.

*** Bug 177477 has been marked as a duplicate of this bug. ***

Similar problem occured while installing RHEL 4 U2 CD set. ( x86_64 ) on HP
Prolient DL145 Generation 2 Server 1 U rack mount with 4GB of ram and two AMD CPUs


Found a workaround in the BIOS for this hardware ...

WORKAROUND
----------
1. Go into the bios -> Advanced -> MCFG Table 
2. Set the option to DISABLED
 

This request was evaluated by Red Hat Product Management for inclusion in a Red
Hat Enterprise Linux maintenance release.  Product Management has requested
further review of this enhancement by Red Hat Engineering, for potential
inclusion in a Red Hat Enterprise Linux Update release for currently deployed
products.  This enhancement is not yet committed for inclusion in an Update
release.

Similar problem occured while RHEL4 U3 with IBM x3755 AMD server with 4GB RAM. 
Workaround add "pci=nommconf" on boot parameter.

If the original problem is fixed and the NIC is not working, I suggest filing
the latter as a separate issue.

I'm closing this bug as a duplicate of Bug 191039.  

*** This bug has been marked as a duplicate of 191039 ***

This was fixed in RHEL 4 U4:
