kernel-2.6.16-1.2107_FC5, NFS server stop working
Last modified: 2015-01-04 17:26:51 EST
Description of problem:
After upgrading to kernel-2.6.16-1.2107_FC5,
NFS server do not respond to mount request.
Version-Release number of selected component (if applicable):
depended on hardware. I have tested this on four PCs.
a. Athlon XP 2200, 8139too : occur
b. Sempron 2600+, e1000 : occur
c. Celeron 950MHz, r8169 : not occur
d. K6-2 450MHz, tulip : not occur
I switched HDD between a and c, then tested again:
a. Athlon XP 2200, 8139too: occur
c. Celeron 950MHz, r8169: not occur
It seems CPU related?
Steps to Reproduce:
1. upgrade to kernel-2.6.16-1.2107_FC5
3. service nfs start
4. exportfs '*:/home'
5. mount foobar:/home /mnt # from other host
NFS server not responding, and cause timeout.
mount: mount to NFS server 'foobar' failed: timed out (retrying).
foobar:/home is mounted on /mnt
does booting with pci=nomsi make this go away?
I tried "pci=nomsi" and got a message "PCI: Unknown option `nomsi'".
All problems are stay there.

dmesg with "pci=nomsi"
Sigh, this option was added post 2.6.16. Please try noapic instead. Thanks.
alternatively, 2108 from http://people.redhat.com/davej/kernels/Fedora/FC5 has
this disabled by default.

dmesg with noapic
I already tried "noapic" and "pci=irqroute", and got same problems.

this is dmesg of 2096, which shows no problem
After upgrading to kernel-2.6.16-1.2107_FC5, my network is dead. Old
kernel-2.6.16-1.2096_FC5 works just fine, though.
Configuration: Athlon 64 X2 on an ASUS A8N-SLI Premium motherboard
alias eth1 forcedeth
alias eth0 skge
where eth0 is not connected to any network, and eth1 is the main interface on a
Results: Boot hangs at NFS mount. Booting kernel-2.6.16-1.2107_FC5 in single
user mode then starting network shows normal routing etc, but pings to machines
on the same subnet fail. Old kernel-2.6.16-1.2096_FC5 works just fine, though.
For what it is worth, I have more or less the same problem as comment #10.
I have a Tyan Tomkat K8E (same nForce Ultra 4 chipset as the ASUS A8N-SLI
I believe) with an Athlon X2 4400+ and the x86_64 version of FC5. Under
.2107 the forcedeth driver doesn't work; under .2096 it does.
- a stock kernel.org 184.108.40.206 works fine.
- 'noapic' and 'pci=irqroute' make no difference.
- on .2107 the driver emits no complaints about life or anything, as far as
I can see; it just doesn't emit or receive packets.
It looks like the original submission was wrt the linux box running an NFS
server. For the record, I'm seeing what appears to be the same problem where
the linux box is the NFS _client_ (the server is Solaris 9). Rebooting into
the previous 2.6.16-1.2096_FC5smp allows me to work.
I tested 2.6.16-1.2109_FC5, and all problems are gone.
NFS server works again, graphical boot works again.
Thank you Dave!
I can confirm that 2.6.16-1.2111_FC5 (which is what I found as current at the
URL in comment #5) fixes the problem for me.
New kernel-2.6.16-1.2111_FC5 fixes the problem for me, too.
