For better or worse, I've been having this problem accross four
identical machines, each with dual quad core processors:
$ cat /proc/cpuinfo
processor : 0
vendor_id : GenuineIntel
cpu family : 6
model : 23
model name : Intel(R) Xeon(R) CPU E5440 @
Some host and guest updates ago, the suspend/resume worked on my Karmic
64 hosts with a variety of guests, including Window 2008 R2, Windows XP
and various Ubuntu releases. Now, when I try to suspend and resume, upon
resume, the machine reboots instead of resuming.
