Maybe it grooks due to being fed with an invalid bus address where it can't DMA do. > Does putting the controller in IDE/legacy mode work OK? Didn't try, and can't easily because it is a headless box sitting in the corner. Speaking of memory: IIRC ahci can do 64bit DMA, which legacy IDE can't. Maybe that makes AHCI trigger the bug while it doesn't happen with IDE? > Oooh, sound. Does it work? Dunno.

Trying to run hvm domains crashes it. Didn't investigate yet why. Could be that it simply depends on changes in xen-unstable and can't work as drop-in replacement for the xen-3.3 qemu-dm version. cheers, Gerd
