Hmmm... I'm not getting any logging on mine.
Do you have a crash dump? I'd need the pdb file for xenpci if you do.
The address being free'd according to the bug check is
0xFFFFFA8000000000, which appears to be allocated here:
XenPCI <-- XenPci_DeviceWatchHandler
XenPCI XEN_INIT_TYPE_RING - tx-ring-ref = FFFFFA8000000000
XenPCI XEN_INIT_TYPE_RING - tx-ring-ref = 16228
I've posted on ntdev mailing list to see if anyone else thinks it
strange that the address is such a round number.
