[ofw] ConnectX functionality is completely broken

Hi,

 

I've compiled svn rev 1450 and tried to install on ws2k3/ws2k8 x64 with
connect x HCA. The BSOD occurs during the installation. The last
revision we tested was 1421. I've recompiled few revisions and found
that changes between rev 1434 and 1435 cause the bugheck.

 

Bottom line - connect x functionality is broken in revision 1435.

 

Regards,

Anatoly.

DRIVER_IRQL_NOT_LESS_OR_EQUAL (d1)

An attempt was made to access a pageable (or completely invalid) address
at an

interrupt request level (IRQL) that is too high.  This is usually

caused by drivers using improper addresses.

If kernel debugger is available get stack backtrace.

Arguments:

Arg1: 00000001cd42b548, memory referenced

Arg2: 000000000000000a, IRQL

Arg3: 0000000000000001, value 0 = read operation, 1 = write operation

Arg4: fffffadfc5e0dd57, address which referenced memory
