Thanks for your reply. After much pulling of hair and wringing of hands and
trial after trial after trial to find corrupted filesystems, I've found that
that the root cause is almost certainly bad memory.
This baffles me because this memory is a replacement for another set of bad
memory and I tested it less than a year ago immediately after installing this
set and it passed all tests more than 10 times without even a single error.
Now, the memory tests fail within 10 seconds of starting memtest86+.
Sorry for the unintentional red herring. Bizarre coincidence that upgrading
to 1.3.85 and a failure of RAM happened simultaneously.
Does this mean anything noteworthy to the openafs developers? I'm not
sure if this file (mm/rmap.c) is a part of openafs or not. Since I've confirmed
bad RAM, it may be meaningless, but thought I'd bring it up since it's so
clear ("kernel BUG at..."):
