First try with version from unstable (1.98+20100804-13), no manual
interventions:
grub-mkdevicemap generated strange device.map (attached).
update-grub used the binary carp in there and put it in grub.cfg
(attached). grub-install on the only non-floppy device in the
device.map worked without problems.
Booting resulted in 8x the following output:
---snip---
Boot device: disk File and args:

Fast Data Access MMU Miss
ok
---snap---
So basically something different happens, but we're far away than we
already were, i.e. no more grub menu or commandline available.
Warm or cold boot doesn't seem to make a difference.
Next try with grub from experimental (1.99~20110106-1): But basically
the same happens, just with three small differences:
a) no "Fast Data Access MMU Miss" but "error: out of memory. error: no
suitable mode found. Illegal instruction" instead.
b) grub-installed issued a warning about embedding not possible in
this setup and that I need to use blocklist instead. It though says
also installation succeeded without error:
6/0/0 root at hz:pts/0 02:01:32 [~] # grub-install '(hd0)'
/usr/sbin/grub-setup: warn: Embedding is not possible. GRUB can only be installed in this setup by using blocklists. However, blocklists are UNRELIABLE and their use is discouraged..
Installation finished. No error reported.
7/0/0 root at hz:pts/0 02:02:41 [~] # grub-install /dev/disk/by-id/ata-ST39120A_7BV080CK
/usr/sbin/grub-setup: warn: Embedding is not possible. GRUB can only be installed in this setup by using blocklists. However, blocklists are UNRELIABLE and their use is discouraged..
Installation finished. No error reported.
8/0/0 root at hz:pts/0 02:03:43 [~] #
But since grub behaves differently afterwards, I think it did write
it on disk.
c) different binary garbage in the device.map (attached)
I'll now try to see if fixing the device map manually (no binary
garbage but hd0 in there instead) helps.
I really wonder where this binary garbage (see attachement) comes
from.
Anyway, next try was to manually edit the device.map to look like I'd
expect it to look:
(fd0) /dev/fd0
(hd0) /dev/disk/by-id/ata-ST39120A_7BV080CK
grub-install still throws the same error messages (in case of the
version from experimental) or not (in case of unstable).
No big change though, just again "Fast Data Access MMU Miss" instead
of "Illegal instruction". Maybe those are interchangable in some way.
Any advice what I could try else? I'll at least stay in contact with
Vladimir for further debugging.
Regards, Axel
