This BUG() assertion did not halt the system, it continued to run the rest of the queued jobs.


I'm not sure why the kernel is showing up as tainted, this is just a stock RHTS install.

Version-Release number of selected component (if applicable):
2.6.31-0.174.rc7.git2.fc12.x86_64
RHEL6.0-20090909.7

How reproducible:
not certain

Steps to Reproduce:
1.start rhts job running /kernel/storage/lvm/snapshot_remove
2.
3.
  
Actual results:


Expected results:
no BUG() warnings from the kernel, the unable to allocation exception messages are normal for this test.

No longer hitting this after testing in snapshot 7 candidate (-42 kernel)
