/hurd/ext2fs.static: device:hd0s0: No such device or address

Please,
The system is on a USB key, grub boots, the hurd starts but stops with this
message:
start /hurd/ext2fs.static: /hurd/ext2fs.static: device:hd0s0: No such device
idem with /hurd/iso9660fs.static !


What happens ?

Thanks


Here is the /boot/grub/menu.lst:

color= 0x01 0x04
default= 0

title=GNU/Hurd (hd0s10)
uppermem=786432

${host-port} ${device-port}
${exec-task} -T typed ${root} $(task-create) $(task-resume)
module /lib/ld.so.1 /hurd/exec $(exec-task=task-create)

title= GNU/Hurd single user or install (hd0s1)

I'm actually having exactly the same problem when trying to boot from an USB external harddrive on a eeePC. I am starting to think this may be (part) of the problem.

Could it be that the default hurd kernel does not support USB-device booting?

Edit: yes, this is the problem as is explained on the Hurd-help mailing list.

I got it to boot properly from the SSD in the eeePC (701 4G, 512 MB RAM), without swap. Have to find a solution for that one, since I understand that mach is difficult that way.
