Description Flags
sysrq-t output from the client when the test hang none

Description Qian Cai 2010-02-05 06:21:15 UTC 
Description of problem:
When running the test case here,
https://fedoraproject.org/wiki/QA:Testcase_nfs_generic_secure

After running the generic fs tests on the mount point for a while, the client behaved strangely, and commands like df, ps aux would hang,


# df
Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/mapper/vg_intels3e314401-lv_root

This bug appears to have been reported against 'rawhide' during the Fedora 13 development cycle.
Changing version to '13'.

Any update?
Comment 5 Jiajian Yang 2011-05-23 07:06:44 UTC 
I tried to reproduce the bug on Fedora 14, 

Kernel 2.6.35.13-91.fc14.x86_64
nfs-utils 1.2.3-6.fc14.x86_64

This bug cannot be reproduced in my environment, i.e. everything goes fine after the fs test. And all the test can be completed.
