I also got kernel missalignment errors..., unfortunately also
a lot of slab debugger errors until the machine rebooted, so
I didn't care too much about the missalignments, but these
could have the same cause?

I now could nail the mem
corruptions down to ACPICA-20051021 by binary search.
It's late, maybe I got something wrong, but I am quite sure the
culprit lies there.

The patch is huge, but maybe it's just one of the other pragmas or
whatever related?:

grep pragma ../ACPICA_20051021.patch
+#pragma pack(1)
+#pragma pack()
+#pragma pack(1)
+#pragma pack()
