Re: [Xen-devel] Re: [Xen-users] svm.c:83:d917 Bad instructionlength 0

[Russ Blaine <russell.blaine@xxxxxxx>]

I traced the issue to __get_instruction_length_from_list() failing to 
copy the instruction from the guest. AMD pointed out the relevant 
changeset, and with that changeset ported to our 3.1.4-based 
implementation, win 2008 can now boot completely without crashing the 
domain.
Thanks...
