Bug 199216

I have this too.  I am not sure whether it is sata_promise or libata.

As Doug above suggested, getting the output from the trace seems beyond my
skill, but I know it can be done if someone has a howto.  I'll do the camera
thing if requested.

This ONLY occurs on .17 kernels, but occurs on all 3 of them.  The FC .15 and
.16 kernels work ok.

Also, I'm having good luck with Debian's .17 kernel, though on different hardware.

One little detail:  This system is a hand-built 2 CPU AMD 32-bit system running
the SMP kernel.  It has 8 hard drives.  OK, laugh.  It's got 2 IDE interfaces, a
sata_promise card, and an LSI 320-2 (PERC4) 64-bit megaraid card.

While this is a dup of Bug 198937 I believe, the description here is more specific.

I am successfully running:

Linux 2.6.16-1.2122_FC5smp #1 SMP Sun May 21 15:18:32 EDT 2006 i686 athlon i386
GNU/Linux

In RH, yum typically 'adds' rather than 'replaces' the kernel package, and both
old and new are available from the GRUB menu.

I tried 2.6.17-1.2174_FC5smp but this problem is not fixed yet.  Do we have to
wait for the 2.6.18 kernel to come out before this is fixed?

This bug was cc'ed to Joachim Selke who says he doesnt really use the driver so
it isnt important to him=and he doesnt have time to fix it??  cant this driver
be reverted to the previous working version??  or should people who use the
sata_promise driver switch to a different distrobution?

Note that I am not a developer. I just added my name to the CC list of this bug
because I have an old test system that is affected by the bug.

Maybe someone should test whether this bug is still there in the current
development version of Fedora. If so, there is a much bigger chance to get some
developer look at it.

This seems to be the problem driver (except that it is the the .17 kernel
version that has the problem).

I have done this.

Using package kernel-2.6.17-1.2566.fc6 obtained on 2006-08-15, I attempted to
boot using that kernel.

Much of what I saw looked the same as the original report.  The system locked up
the same.  But the final errors were different when it locked up; though it was
at about the same point in the boot process.  Several storage drivers seem to
load at once at this point.

Is there a race condition here?

One thing that I think is odd, this is not a hard lock.  Ctrl-Alt-Del suffices
to reboot.  Is that useful?

I took pictures, but they did not come out.  I can try again if needed.

So if it happens in the current DEVEL kernel, what does that mean?  What happens
next, and how can I help?

Someone then should change the version field of the bug description to "devel".
I am not allowed to do this but Doug should. He is the reporter of this bug.

This of course does not guarantee that a developer looks at this bug. But at
least it is clear now that this bug is not fixed already in the most recent
kernel version.

Since the devel version of Fedora changes day by day you should try periodially
whether the bug is still there. It might happen that the bug is fixed
unwittingly some day.

I noticed a similar bug in the ata3 driver on another system running fc5, I
opened this bug 2 months ago and I have only gotten emails from other users
confirming the same bug,  is anyone at fedora even looking at this issue?

Hello?  I've verified that this bug *still* occurs in the released 2.6.18 kernel
(1.2200.fc5smp).  Now I can't upgrade to FC6 until this bug is fixed; from my
point of view this is a "blocker" bug.

I really didn't want to wave my credentials around, but I am an (outrageously
highly paid) Enterprise distribution tester for both Novell and Red Hat.  I can
also be reached as jason_mack after Tue 2006-10-24.

Just tell me what you need next, and I'll get it for you.

The bug's trace is shown clearly on the screen but is not dumped to a file
anywhere that I can see.  Let me know the technique and instructions for getting
the info, and I will.  I've tried using a digital camera to get it, but the
images are always "shaky" to the point of unreadability.

Note:  I am using the stock Red Hat kernels, these are not custom compiled.

In the meantime, here is dmesg from the known good 2.6.16 kernel.

Trace of this failure

Trace captured.  This is the kernel BUG Oops output captured via serial port
for 2.6.18-1.2200.fc5.	Note this is the UP kernel, I can also get SMP kernel
output if needed.

Special thanks to Fedora Board member Matt Domsch for lending guidance and a
cable.

Lovely.

static u32 pdc_sata_scr_read (struct ata_port *ap, unsigned int sc_reg)
{
        if (sc_reg > SCR_CONTROL)
                return 0xffffffffU;
        return readl((void __iomem *) ap->ioaddr.scr_addr + (sc_reg * 4));
}

sc_reg = SCR_CONTROL = 2, so ap->ioaddr.scr_addr must be zero for us to
dereference NULL+8.  Why isn't scr_addr set here yet?

Jason or someone, please attach an lspci -vv and lspci -vvn so we know which
cards this is.

I suspect the "disabling port" message is the culprit, coming from
ata_bus_reset().  This is a 3-or-more port card, but ap->ioaddr.scr_addr didn't
get set in pdc_ata_init_one() for it...

output of lspci -vv

It might be important for me to note that my Promise card has a SATA drive
attached to each SATA port, but that the IDE controller is not actually being
used.

lspci -vvn follows.
