dmesg output

Shuttle DS81 barebone died all of a sudden and was replaced by DS81L.
System came up well, but Firefox created intensive CPU usage.
Since reinstall of Firefox I can not get the window manager to run.
System boots, has some glitches on the login screen (user names not displayed).
After Login, Desktop incl. panels appear, but disappear prior the mouse becomes
responsive. Desktop files remain.
During my investigations I discovered these erros and were unable to resolve
them. I actually downgraded the kernel w/o any change.

I appretiate any hint or solution, this is very strange in my opinion.
Thanks
