Package: grub-pc
Version: 1.96+20090808-1
Severity: important
I have a machine running Xen 3.2 (from the xen-hypervisor-3.2-1-amd64
package). Previously I was using grub-pc 1.96+20080724-16 to boot the
hypervisor with a Xen-Dom0-enabled 2.6.26 Linux kernel (from the
linux-image-2.6.26-1-xen-amd64 package); this was working fine.
When I upgraded grub-pc and grub-common to 1.96+20090808-1, this broke the
booting of the Xen 3.2 hypervisor with an early fatal page fault error
message like described in the following:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=516610
http://lists.xensource.com/archives/html/xen-users/2009-02/msg00768.html
Note that I'm merely referring to the described symptoms. I have no way
of telling whether these cases are also caused by a GRUB incompatibility.
In my case, however, this is definitely the cause, since downgrading
grub-pc and grub-common to 1.96+20080724-16 restores Xen 3.2 to a working
state.
Note further that I cannot upgrade to Xen 3.4 because, even though it does
not hang with an early fatal page fault error with the latest GRUB, the
Linux kernel then hangs during hardware detection, for possibly unrelated
reasons.
The currently latest version of GRUB, 1.97~beta2-1, too, makes Xen 3.2
hang with identical symptoms. I see that there were many other GRUB
releases between 1.96+20080724-16 (last known good) and 1.96+20090808-1
(first known bad), but I wasn't able to test them.
