Hi,
I have been bitten a few times by the BUG() in unlock_page(), both
with 2.4.19-rc3-xfs and 2.4.19-xfs (the latter checked out from SGI's
CVS on Aug 10). The system is SCSI-only, with a raid5 array as an LVM
physical volume and XFS on all the volumes.
Software-wise it's Debian Woody, but the kernel is compiled on a Sid
box with gcc 2.95.4-16.
Attached are the decoded oops, the module list and the config.
