Description Chris Nighswonger 2006-11-30 19:13:42 UTC
Description of problem:

     The problem occurs in exactly the same circumstances on two otherwise very
stable different hardware platforms. When performing multiple mount/umount of
network shares of type 'cifs' the initilization of SELinux causes the kernel to
crash. The problem is reproducable on these two machines with regularity.
However, various amounts of log are available depending on how fast the kernel
killed itself.

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

System A: 2.6.18-1.2849.fc6

System B: 2.6.18-1.2798.fc6

How reproducible:


Steps to Reproduce:

     Repeatedly mount/umount a network share of type 'cifs' using a mount
command similar to this:

mount -t cifs //192.168.x.x/sharename /mnt/sharename -o\

     ...along with a simple 'umount /mnt/sharename'

Actual results:

     Eventual kernel crash.

Expected results:

     Stable system operations.

Additional info:

     Please feel free to contact me for further information. I am willing to
assist with the debug process.

Comment 3 Chuck Ebbert 2007-06-07 17:49:04 UTC
Can the reporter test the latest kernel (2.6.20-1.2952 or later)
and report? Many bugs have been fixed in CIFS.

Comment 4 Jeff Layton 2007-12-29 12:17:47 UTC
This appears to be a dupe of bug 224359, please reopen if this is still
occurring in recent kernels.
