Package: grub-pc
Version: 1.97~beta4-1
Severity: grave
Justification: renders package unusable
Installing grub-pc on my Dell PowerEdge 2950 hangs during postinst:
Setting up grub-common (1.97~beta4-1) ...
Installing new version of config file /etc/grub.d/30_os-prober ...
Setting up grub-pc (1.97~beta4-1) ...
(need ctrl-c)
I tried with 1.97~beta3-1 and 1.97~beta4-1, same result.
Two (similar) machines do this. I have 4 other older poweredge
2950 where grub-pc installs fine. Not sure what hardware difference
could explain this, the software installation is pretty much the same.
After trying to fix this a couple time and having to abort with ctrl-c,
I see this in ps:
0 D root 14935 1 0 80 0 - 944 ? 07:26 ? 00:00:00
grub-mkdevicemap --no-floppy
0 D root 15311 1 0 80 0 - 944 ? 07:33 ? 00:00:00
grub-mkdevicemap --no-floppy
0 D root 15498 1 0 80 0 - 944 ? 07:58 ? 00:00:00
grub-mkdevicemap --no-floppy
0 D root 15853 1 0 80 0 - 944 ? 07:58 ? 00:00:00
grub-mkdevicemap --device-map=/tmp/device.map.pAT8GlfT --no-floppy
0 D root 15893 1 0 80 0 - 944 ? 08:01 ? 00:00:00
grub-mkdevicemap --no-floppy
So it looks like grub-mkdevicemap hangs here.
These processes are not killable.
I thought of rebooting the machine to cleanup these processes
but I don't konw what the partial installation actually broke
from my old grub1 install.
device.map was left empty. I restored it.
Which other files should I check before I can reboot?
thanks,
Brice

There are multiple of them because it failed on install, then again on
apt-get -f install, then again on dpkg --configure -a, ... I guess one
process hung during each failure.

The output is actually very simple:

close(3) = 0
mprotect(0x7fdf767c3000, 16384, PROT_READ) = 0

stat("/dev/.devfsd", 0x7fffd7d52420) = -1 ENOENT (No such file or

open("/dev/hda", O_RDONLY
/dev/hda is the cdrom, and it seems it got some problems:

I just remove /dev/hda manually and the package successfully configures now.
Reboot went fine. Now that the cdrom isn't screwed up anymore in the
kernel, I can reinstall grub-pc without problem.
Looks like there's no bug here (except maybe in my cdrom hardware and/or
kernel cdrom driver).
Thanks for the hint!
