Description of problem:
We've seen two occurrences of this panic while running
HP's internal "busy" and "hazard" tests.  It looks like
the same problem reported here:


The first sighting was on a RHEL3 U2 kernel with my
patch for

The second sighting was on a kernel without my patch.
Unfortunately I don't know the provenance of the kernel;
it claims to be 2.4.21-11.EL.

Comment 1 Rik van Riel 2004-06-25 01:34:40 UTC
Looks suspiciously like it could have been fixed already in the U3
stream, by an upstream inherited patch to inode.c.  Ernie, could you
please give Bjorn the latest RHEL3 kernel so he can verify that it is
indeed gone ?

Comment 2 Ernie Petrides 2004-07-02 22:06:46 UTC
A fix for this problem has been previously committed to the RHEL3
U3 patch pool on 9-Jun-2004 (in kernel version 2.4.21-15.9.EL).

Comment 3 John Flanagan 2004-09-02 04:31:52 UTC
