Hi James:
 
      I am still working on the blue screen issue.
 
     This time I found 6 more machines to test. Two machines confronts  a new blue screen in
2 days long test.
 
KERNEL_STACK_INPAGE_ERROR
stop:0x00000077(0xc0000185,0xc0000185,0x00000000,0x009d9000)
 
 
      Attached is the log, cp1, 9, 15, 16, 17, 20, are broken, and has the log like:
-----------------------------
12944494073046: XenVbd --> XenVbd_HwScsiResetBus
12944494073046: XenVbd     IRQL = 31
12944494073046: XenVbd     Completing in-flight srb 892C7058 with status SRB_STATUS_BUS_RESET
12944494073046: XenVbd <-- XenVbd_HwScsiResetBus
12944494073046: XenPCI     Grant Entry 16382 for ISCS still in use by ISCS
12944494073046:
*** Assertion failed: !xpdd->gnttb l_table[ref].flags
***   Source File: e:\download\win-pvdrivers.hg\xenpci\gnttbl.c, line 120
 ---------------------------
 
Thanks.
