Hello Don,

I did try some things here. pci=nomsi didn't work really, but I think it
decreased the rate of stucks, even though I'm not sure. My BIOS is a
Phoenix TrustedCore with version number PG2G3A08, should be from 7/2009
or so.

I will try my next boot with hpet=disable and report my results. Thanks
for your help!
