oops, 2.4.26 and jfs

[Chris Stromsoe]

This morning during a cron run while doing a find across /, I got the
following oops.

There is only the one jfs partition on the machine It has 607376 inodes in
use out of 17524128 total, and 27350660 bytes out of 35806700.  The
partition is on top of a 3-disk md RAID5 that is under constant pressure
(it's a virus quarantine).  All processes trying to do anything with the
partition are stuck in D state.

Right before the oops, I logged:

May 26 06:28:10 begonia kernel: __alloc_pages: 0-order allocation failed (gfp=0x1f0/0)

May 28 06:28:50 begonia kernel: __alloc_pages: 0-order allocation failed (gfp=0x1d0/0)

I don't have correct modules or System.map output; I rebuilt the
kernel/modules/system.map yesterday to prepare for a reboot, and
over-wrote the System.map and modules with the new files.
