Bartlomiej's workaround (mount with "barrier=0") doesn't seem to help to
workaround the problem. I had one BUG/oops/panic (the same as reported)
after 96 hours of uptime and another one after only a few minutes of uptime.

Some more info on the disk setup (all partitions including root):

hda(1)/hdc(1)/hde(2) <-> 2x md raid5 <-> dm-crypt <-> lvm2 <-> ext3

(1) AMD8111
(2) PDC20268

Swap is set up as:

hda(1)/hdc(1)/hde(2) <-> dm-crypt <-> swap

(1) AMD8111
(2) PDC20268

I could start trying to find out where the problem started but will have
to start with 2.6.13 as I had other problems with earlier kernels.
Please let me know if you want me to go through this as each test run
will probably take a few days.

BTW: To prevent bit error speculations, just before initially reporting
the problem I did run >200 hours of memtest with no errors and all
memory is ECC.

If it helps, here is some information from /proc/interrupts:
