I have tried with 10.0-RELEASE again, and the problem persists.
Sometimes a session runs for 8hours without issues, sometimes is reboots
after 2min.

Other issues I am seeing is spontaneous lockups of X. It looks like a
hang, but than after 10-30s there is a flicker and regular operation is
resumed (happened only twice up till now).
Another weird thing I noticed, is that video doesn't work right. No
matter whether I pick XV or GL, with the new drivers video is stuttery
at best. This happens on mplayer, vlc and xine.

Unfortunately I do not have SWAP on this machine, as I have only a small
SSD, but lots of RAM. There is no way to get a crash dump then, is there?

Thanks for your help!

Best,
Hannes
