Description Olaf Fraczyk 2004-07-09 05:31:28 EDT
Description of problem:
Complete system freeze.

Filesystem - XFS for all partitions.
EXT2 partition on DVD-RAM mounted - for backup.
Exported read-only small nfs for X-Terminals.
While doing backup and bzipping it - high load, with 1 NFS ->
X-Terminal client, 3 samba clients the system freezes.
I didn't see it on vanilla kernel 2.6.5-rc3 (the latest used by me
before switch to redhat/fedora kernel).
I didn't see it  on RH/Fedora kernal if no NFS client is active.

Just now I reverted to vanilla 2.6.5-rc3.

Version-Release number of selected component (if applicable):


How reproducible:
Hard to say. 

Steps to Reproduce:
1. Not easy to explain. Read the Description of the problem.
Actual results:
System freeze

Expected results:
No system freeze :)

Additional info:
I'll attach kernel messages from log.

2.6.6-1.435.x.x is not up-to-date with the latest XFS updates, FWIW.
Could you try a kernel from one of the following sources and let us
know if the bug is still present? Thanks.

+ rawhide (a.k.a. FC-devel)
+ FC 3 test 1

I'm seeing something similar to this, using the 2.6.10 kernel with
Fedora Core 3
patches. It's less frequent than in 2.6.9, but it still isn't fixed.

I can trigger it pretty consistently by copying an 8 gigabyte file
/dev/random output) using an NFS client, from one NFS export to
another, both on
the same XFS filesystem. The filesystem resides on a software RAID-5
device. The
kernel panic usually happens within 3 attempts.

The crash does not happen if I perform the same operation (client file
copy -
same file - between NFS exports) on an ext3 filesystem.

I'll see if I can get a trace, but I'm pessimistic. The last 60 lines
shown in
my local console are meaningless (seems like a crash in crash
handler), NIC
driver does not support netconsole, no SCSI devices for raw core dump
support, etc.

I've added the same comment in SGI's bug.
Comment 5 Hans Petter Jansson 2005-01-18 18:53:42 EST
The full kernel version is "2.6.10-1.737_FC3". Sorry for bad line
breaking in my last comment.
Comment 6 Dave Jones 2005-04-16 00:37:29 EDT
Fedora Core 2 has now reached end of life, and no further updates will be
provided by Red Hat.  The Fedora legacy project will be producing further kernel
updates for security problems only.

If this bug has not been fixed in the latest Fedora Core 2 update kernel, please
try to reproduce it under Fedora Core 3, and reopen if necessary, changing the
product version accordingly.

Thank you.
