Package: grub-pc
Version: 1.98+20100614-1
Severity: critical
Hi,
after the upgrade:
grub-pc 1.98+20100527-2 1.98+20100614-1
system won't boot anymore. Grub prints:
Unaligned pointer 0x4c191bea - press any key
After pressing a key it says "No operation system found" - seems grub
quit. Downgrading to 1.98 and running grub-setup /dev/sda makes the
system boot again.
