Ok, I did not have --disable-linux-groups yet, if I add that to the configuration, it boots further. However, it then looks identical to what I saw with SMP, i.e., booting takes much longer and then at some point I get a "lost interrupt" every 10 seconds (I changed the boot device from hd0 to wd0): |warning: dmalloc(4096) requested with 10000 alignment, bumping up size |[ 47.5800050] cd0(piixide0:1:0): using PIO mode 4, DMA mode 2 (using DMA) |[ 47.6700050] WARNING: 10 errors while detecting hardware; check system log. |piixide0:0:0: lost interrupt |[ 50.6800050] type: ata tc_bcount: 512 tc_skip: 0 |piixide0:0:0: lost interrupt |[ 60.7100050] type: ata tc_bcount: 512 tc_skip: 1 I use the following KVM command-line right now: kvm -display curses -net user,hostfwd=tcp:127.0.0.1:2020-:22 -net nic,model=e1000 -drive file=hurd-unstable.img,cache=writeback,format=raw -m 2G Michael
