I am using 2 160Gb Maxtor disks in geom_mirror. With 6.3 it runs fine. I 
upgraded to 7.0-RELEASE and after install problems started. Disk TIMEOUTs
freezed the box as soon as I initiated a lot of disk activity (e.g. make
buildworld of building a kernel).

I 'downgraded' the box to 6.3 again (had to rebuild the mirror because it was
touched by a newer gmirror) and now the problems have gone again. I have the
strong impression it is not hardware bot rather 7.0-RELEASE related.
Actually I want to get rid of the box at home (want to carry it to a datacenter)
but if it can be helpfull I am willing to have it for another week or two at
home to upgrade/downgrade/etc. with it.

My dmesg (6.3 again):
