Ok, will try that, too. Though this will be only possible on our
secondary machine.

I've had a look into src/sys/dev/aac/* and it looks like there are
no changes since freebsd-6.2-release.

Here it happens quite often, if I run the testdisks.sh shellscript
that does heavy i/o.

Ah, we had that on another server, too. This seems to be normal freebsd
behaviour when it wants to be repaired :-)

I think I'll give it again a try but will search in parallel for a scsi
card replacement (see other mail).

What also makes me wonder is that many times the system has to rebuilt
the raid1 after a crash. looks like they are written asynchronously.
