[Xen-devel] crash when domain is restored

[Peri Hankey <mpah@xxxxxxxxxxxxxx>]

Hello

I hadn't yet investigated save/restore, but it seems not to work for me. 
Running Mandrakelinux 10.1 (ish - updated not reinstalled) on an AMD 
ATHLON 2400 I have a crash restoring the domain:
   root@xen0# xm save aaa aaa.saved
   ...
   root@xen0# xm restore aaa.saved

The console output is as follows:

Unable to handle kernel paging request at virtual address 0000c000
printing eip:
