After some experimenting, it seems to be a gnumach problem, not hurd
or grub. It couldn't be grub since I was already using the 0.5.95
boot floppy for some time, and it could always boot the "old" hurd
successfully.

At the moment I have the following in my /boot directory:

gnumach_1.2-2.gz
gnumach_1.2-5.gz
serverboot_20000130.gz
serverboot_20000803.gz

When I use gnumach_1.2-2, everything boots perfectly, using either
serverboot_20000130.gz or serverboot_20000803.gz. Since the
serverboot.gz file comes from the hurd deb, running newer hurd
servers on top of an "old" gnumach seems to be no problem.

When I use gnumach_1.2-5, I get the "Root device `sd2s2' does not
exist" error, also independent of which version of serverboot.gz is
used. Single- or multi-user mode doesn't make any difference either.
Specifically, I get the following boot messages (at the end, the
first part scrolls away to quickly, any way to log that?):

Partition check (DOS partitions):
 sd0: sd0s1
 sd1: sd1s1 sd1s2 sd1s3 sd1s4
 sd2: sd2s1 sd2s2
 sd3: sd3s4
com0: at atbus0, port = 3f8, spl = 6, pic = 4. (DOS COM 1)
com1: at atbus1, port = 2f8, spl = 6, pic = 3. (DOS COM 2)
Root device `sd2s2' does not exist!
Root device name? [sd2s2]

Note how the partition check works OK. Is the "Root device name?"
question handled by gnumach or by serverboot?

For the time being, I'll just keep using a copy of gnumach_1.2-2,
since all my hardware works properly with it. I can upgrade other
components using dselect without much problems.

I've also tried installing from scratch with the new
gnu-20000913.tar.gz file, but since that comes with gnumach_1.2-5,
I'm getting the same error.
