With grub-pc 1.98+20100614-2, I had the same failure, with unaligned pointer 0x4c19a146.
This occurred before any other output to the screen by grub. No menu, no shell, nothing. downgraded to grub-pc 1.98+20100602-2 (and grub-common 1.98+20100602-2) and the problem went away. The problem occurred after an upgrade from grub-pc (and grub-common) 1.98+20100602-2 to 1.98+20100614-2. This was on a Thinkpad T43. bjb -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble? Contact listmas...@lists.debian.org
