It is the same.

Interesting. My memory from back in January was that it occurred for me
when I was fiddling with the setup.

If you have a diskette drive, you can use my DumpTrapScreen tool. I
recommend you make room for a trap dump partition. This will be needed
for any serious diagnostic work on this kind of problem. PMDF is the tool
of choice for analyzing trap dumps. This should be sufficient for
tracking down this one. I don't think that the kernel debugger will be
needed for this.

Given where the error occurs, it appears that GenPrism expects to be the
caller to pass a buffer pointer and this did not happen.

My notes are far from complete, but the ring 3 stack shows:

# Base Ptr Parameters Caller
-------- ---------------- ------
%0007c40c 0003 0000 0080 0000 0064 0000 0000 0000 WIFISTAT nwepgen +
16b
%0007c44c 0003 0000 c552 0007 002a 0000 0080 0000 WIFISTAT
WLanGetSSIDInfo + 23
%0007c468 0001 0003 0000 c552 0007 0000 0000 0000 Unknown c588 0007
31a8 0001
%0007c588 0000 301f 8103 5260 0bf4 0f72 04b8 52ac Unknown 0000 0000
0000 0000

so I have assume that wlanstat is trying to fetch the SSID from the driver
when the trap occurs.

The trap in GenPrism occurs during a string copy because es:edi is bogus.

Regards,

Steven
