Package: grub-pc
Version: 1.98-1
Severity: important
Tags: squeeze
Upon manual invocation or through automatic upgrades of grub-pc, grub-install
does not work. The error comes from grub-probe which segfaults on the followin
commandline : /usr/sbin/grub-probe --device /dev/mapper/vg2-boot
--target=partmap However, while a "Segmentation Fault" message is printed,
grub-install still reports that "Installation finished. No error reported." I
only experience that issue on my amd64 box, where I have a lvm on gpt setup.
The last lines or grub-probe follow. open("/dev/hdc1", O_RDONLY) =
