Hi !
I am implementing WMI on a SCSI Miniport and I am facing the following
problem -
As per the docs and the SCSI Miniport sample in the DDK I am doing -
- Register as a WMI data provider by setting the flag in
PPORT_CONFIGURATION_INFORMATION
ConfigInfo->WmiDataProvider = TRUE; in my FindAdapter routine. - Created the MOF file and compiled it as a binary resource in the
miniport’s binary image. - Implemented the required HwScsiWmiXxx callback routines.
However when I install and run my driver, I observe that I do not get
any calls to
the StartIO routine with SRB_FUNCTION_WMI. Also, while the SCSIPort is
trying to initialize, it bugchecks.
I guess, SCSIPORT is registering as a WMI data provider and is missing
something while doing so.
I am trying to figure out whats that ? ? ? am I missing something here
? ? ?
Any help would be great !
Thanks

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.
Some common problems are exception code 0x80000003. This means a hard
coded breakpoint or assertion was hit, but this system was booted
/NODEBUG. This is not supposed to happen as developers should never
have
hardcoded breakpoints in retail code, but …
If this happens, make sure a debugger gets connected, and the
system is booted /DEBUG. This will let us see why this breakpoint is
happening.
An exception code of 0x80000002 (STATUS_DATATYPE_MISALIGNMENT) indicates
that an unaligned data reference was encountered. The trap frame will
supply additional information.
Arguments:
Arg1: c0000005, The exception code that was not handled
Arg2: f84894e8, The address that the exception occurred at
Arg3: f897cad0, Exception Record Address
Arg4: f897c7d0, Context Record Address
Debugging Details:
***** Kernel symbols are WRONG. Please fix symbols to do analysis.
