| I ran fsck to fix errors on this disk in the last week,
| but it appears the problem still exists.
Could you unmount and run xfs_repair please, and capture the output.
(fsck is a no-op on XFS).
I spent some time last week on this, just didnt get a message out to
you - my disassembly of the code around the point of your panic gave
me no real clues - I think (not 100% sure though...) its an xfs_inode
NULL pointer deref, but my disassemly didnt have instructions quite
lining up with yours (probably different gcc versions). I'm taking a
stab in the dark that you may have a corrupt inode nlink field ondisk
for a particular inode, but thats just a guess at this stage based on
the oops.
Can you try figure out more exactly when this started? (is there a
kernel version you've reverted back to where it doesn't occur?). If
there is anything unusual in the xfs_repair output, pls add it here.
Also, is it always the xdm process (from yoour trace) that triggers
this or does it vary? And are your stacktrace EIP always in xfs_read
as in your hand-copied trace here?
thanks!
