Frequent "unaligned access", an init that dies, ... (fwd)
Oops, that was not supposed to go to debian-devel, but to
debian-alpha.

Things are not going as well as they should...
I get frequent "unaligned access" messages:

Should I be worried about this?
I've had the system die on me a few times (resulting in
broken filesystems and such), with error messages indicating
"unable to handle kernel paging request" (or words to that
effect), "idle task may not sleep", and something that
indicated that init was behaving badly or crashing.
This has usually happened while I was installing packages
(by hand, using dpkg), but I haven't yet found a good way of
repeating it -- it takes a few hours per iteration.
I use a self-compiled kernel, which seems to work pretty
well with the Red Hat installation. It's version 2.0.30; I
guess I should try 2.0.31 as well, but that will have to
wait a day or two.
