[Xen-devel] Vista crashed when do the ltp memory testing under domain 0

["Steven Hu" <learn.hu@xxxxxxxxx>]

Hello,
When run x86_32 SMP Vista HVM guest  and run LTP memory stress testing
under domain 0, after some time, vista will blue screen with this
message:"a clock interrupt was not received on a secondary processor
within the allocated time interval" with Bug Check 0x101.

This issue can also be reproduced copy big files under vista for a
long time.( not alway ).

Could anyone give some idea about this issue? According to my
understandng,  when domain 0 do the DMA disk access, some timers are
lost. It is related the APIC timer interrupt.
Thanks.
