Bug#488375: grub-probe hangs

Sat Jun 28 12:36:44 UTC 2008

Package: grub
Version: 0.97-41
Severity: important

When trying to install the latest kernel update, the command
   /bin/bash /usr/sbin/update-grub 2.6.25-2-amd64 /boot/vmlinuz-2.6.25-2-amd64
hangs indefinitely. After some checks, it becomes clear that the command
   grub-probe --device-map=/boot/grub/device.map -t device /
is responsible. It is trying to open /dev/fd0. There is no such device, nor
was there ever one on this machine. However, the kernel update never
failed before. Removing the offending entry from device.map seems to fix
the problem.

# groot=(hd0,1)

## should update-grub create alternative automagic boot options
## e.g. alternative=true
##      alternative=false

## should update-grub lock alternative automagic boot options
## e.g. lockalternative=true

## additional options to use with the default boot option, but not with the
## alternatives
## e.g. defoptions=vga=791 resume=/dev/hda5

## should update-grub lock old automagic boot options

## Xen hypervisor options to use with the default Xen boot option
# xenhopt=

## Xen Linux kernel options to use with the default Xen boot option

## altoption boot targets option
## multiple altoptions lines are allowed
## e.g. altoptions=(extra menu suffix) extra boot options
##      altoptions=(single-user) single
# altoptions=(single-user mode) single

## controls how many kernels should be put into the menu.lst
## only counts the first occurence of a kernel, not the
## alternative kernel options
## e.g. howmany=all
##      howmany=7
# howmany=all

## should update-grub create memtest86 boot option
## e.g. memtest86=true
##      memtest86=false
