Hi All,
I have few Hosts with Windows Server 2003 SP1 and drivers of MPIO 1.16
installed.
From time to time when I reboot the Host I get BSOD 7E at shutdown
process.
I perform bug analyze and receive the next stack:
1: kd> !analyze -v
SYSTEM_THREAD_EXCEPTION_NOT_HANDLED (7e)
This is a very common bugcheck. Usually the exception address pinpoints
the driver/function that caused the problem. Always note this address
as well as the link date of the driver/image that contains this address.
Arguments:
Arg1: c0000005, The exception code that was not handled
Arg2: 80840284, The address that the exception occurred at
Arg3: f78d6934, Exception Record Address
Arg4: f78d6630, Context Record Address
BUGCHECK_STR: 0x7E
CURRENT_IRQL: 0
LAST_CONTROL_TRANSFER: from 80920d39 to 80840284
STACK_TEXT:

Using the parameters of the ObpQueryNameString function I receive that
this is the device object of the MPIOControl and the corresponding
DevNode is a parameter passed on function ObfReferenceObject on the same
stack:
1: kd> !devstack 8975f028
!DevObj !DrvObj !DevExt ObjectName
8975f028 \Driver\mpio 8975f0e0 MPIOControl
897c0a80 \Driver\PnpManager 897c0b38 00000026
!DevNode 897c0930 :
DeviceInst is “Root\MPIO\0000”
ServiceName is “mpio”
Can any body tell me if there is some bug on the MPIO drivers than
should cause this problem?
Thanks,
Gabriel.
