fsstress panic log
Description of problem:
Run fsstress test on btrfs may cause kernel bug and panic.
Attachment is console log.
Version-Release number of selected component (if applicable):
[root@amd-drachma-01 ~]# uname -a
Linux amd-drachma-01.lab.bos.redhat.com 2.6.32-27.el6.x86_64 #1 SMP Tue May 18 12:25:26 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux
[root@amd-drachma-01 ~]# rpm -q btrfs-progs nfs-utils rpcbind
Also on RHEL6.0-Snapshot-5, that is 2.6.32-28.el6.x86_64
Steps to Reproduce:
1. Schedule /kernel/filesystems/btrfs/fsstress in rhts or beaker
2. Or yum install rh-tests-kernel-filesystems-btrfs-fsstress
then cd to /mnt/tests/kernel/filesystems/btrfs/fsstress, make run manually
kernel bug and panic
Pass test all the time
rhts job link
beaker job link
And there is a PASS test in beaker, but fsstress process may be stuck.
It looks like there was not actually a bug or a panic, but there was a soft lockup and a WARNING due to list corruption, which is bad enough ...

been denied for the current Red Hat Enterprise Linux release.
** If you would still like this issue considered for the current
release, ask your support representative to file as a blocker on

Josef, can you validate that this does not happen in the current 6.0 builds and close it if not? If it is still an issue, we should reflag this for 6.1 since we are not going to have tech preview items be blockers unless really severe.
I ran xfstests against the updated btrfs in RHEL6 and I didn't get any panics (it runs fsstress), so I'm going to close this.
