Package: grub-pc
Version: 1.96+20080724-10
Severity: grave
Justification: renders package unusable
A system became unbootable after installing a new kernel without making any
other i
changes. grub just reported:
free magic is broken at 0x90c00: 0x2e647362
The reason seems to be as obscure as the length of the kernel image name. This
caused
one of the lines in the new grub.cfg to be exactly 128 bytes (there are two
tab's here):
linux /boot/vmlinuz-2.6.27-git-ahci-1-amd64
root=UUID=0ebb368d-b15e-4796-9029-9adfced061a0 ro console=tty0
console=ttyS0,9600n8
and this again caused grub to crash. Changing the entry by e.g adding a space
will make
the system bootable again, but I still feel this justifies a grave severity
given the
need to boot from some other medium to fix the error. And not to mention the
complete
unexpected side effect of a kernel image name...
Google told me that the bug has been reported to grub-devel with a patch:
http://lists.gnu.org/archive/html/grub-devel/2008-07/msg00601.html
I believe this needs to be fixed before lenny is released. Thanks.
