Red Hat Bugzilla – Bug 217915
kernel BUG at lib/list_debug.c:70! invalid opcode: 0000 [#1] SMP
Last modified: 2007-11-30 17:11:50 EST
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
Version-Release number of selected component (if applicable):
System A: 2.6.18-1.2849.fc6
System B: 2.6.18-1.2798.fc6
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'
Eventual kernel crash.
Stable system operations.
Please feel free to contact me for further information. I am willing to
assist with the debug process.
This is the same as bug 214622.
A couple other people have reported this bug too...
People were also getting bug 216001 which has a similar trace. One of those
reporters was using cifs, but i'm not sure about the other.
