Bug#592080: grub reports "read errors on block" on startup

Package: grub-ieee1275
Version: 1.98+20100804-1
Severity: normal

Hi,

after the message “Welcome to GRUB” I get four lines saying “read errors
on block <big number>.” Then the normal menu starts and I can boot my
system. I'm running the newest version, i.e. the version string displayed
in the menu matches the version of the Debian package.

Bye, Jörg.
