Hello list,
Did an update to the latest AMD drivers
(11-9_vista64_win7_64_dd_ccc_ocl) and was pleasantly surprised to find
that I can reboot my passthrough domU!
Firstly, the reboot was triggered involuntarily shortly (20
seconds) AFTER the SUCCESSFUL driver update. The only thing logged was
this:
(XEN) io.c:194:d5 MMIO emulation failed @
0010:fffff800036c7d00: 0f 28 04 10 0f 28
The domU and qemu spontaneously disappeared (the qemu log just
stops there and logs nothing), and reappeared, as a new domU instance
was automatically spawned.
This first reboot would be unsuccessful, encountering a BSOD at
the pulsating logo stage:
"Attempt to reset the display driver and recover from timeout failed"
The second try would be successful.
The awesome thing is, I tried normally rebooting the domU a few
times after that, no problems! =)
Attached is the full log captured between the start of the driver
update and the second (successful) reboot.
Liwei
