AOL^H^H^H I too have experienced this when trying to boot oskit-mach 
(current HEAD of gnumach branch, whatever we should call it). I think I 
get as far as reading the different partitions of hd0, but then the 
machine simply reboots.

The best results (boots further and does not automatic reboot) is when I 
use the good old serverboot method. I haven't gotten any further than 
Ognyan in debugging it. If I get some time over tomorrow I'll set a few 
breakpoints in bootstrap.c and try to find out where things go wrong.

Grub entries that I've tried:

root (hd0,1)
kernel /boot/oskit-mach.gz -- root=device:hd0s2
module /hurd/ext2fs.static --readonly \
   --multiboot-command-line=${kernel-command-line} \
   --host-priv-port=${host-port} \
   --device-master-port=${device-port} \
   --exec-server-task=${exec-task} \
   -T typed ${root} $(task-create) $(task-resume)
module /lib/ld.so.1 /hurd/exec $(exec-task=task-create)

root (hd0,1)
kernel /boot/oskit-mach.gz -- root=hd0s2
module /hurd/ext2fs.static --readonly \
   --multiboot-command-line=${kernel-command-line} \
   --host-priv-port=${host-port} \
   --device-master-port=${device-port} \
   --exec-server-task=${exec-task} \
   -T device ${root} $(task-create) $(task-resume)
module /lib/ld.so.1 /hurd/exec $(exec-task=task-create)

root (hd0,1)
kernel /boot/oskit-mach.gz root=hd0s2
module /hurd/ext2fs.static --readonly \
   --multiboot-command-line=${kernel-command-line} \
   --host-priv-port=${host-port} \
   --device-master-port=${device-port} \
   --exec-server-task=${exec-task} \
   -T device ${root} $(task-create) $(task-resume)
module /lib/ld.so.1 /hurd/exec $(exec-task=task-create)

root (hd0,1)
kernel /boot/oskit-mach.gz -- root=hd0s2
module /boot/serverboot.gz
