I will try running memtest86.

But by browsing through this list I found the thread "sk0: watchdog timeout"
and the problem described there is quite similiar to what I get here. So
perhaps this bug in the sk driver is also the cause for my trouble here?!

Can I somehow use this patch for sk0 _without_ changing everything to 
-current? Acutually, I wanted to stay to 6.1-RELEASE...
