My partner has a machine that seemingly just doesn’t like to be debugged.
The machine is a dual x64 machine, but it is running XP Pro 32 bit.
When I connect windbg from my machine to this thing using a standard serial
debugging cable and then reboot the dual processor machine (specifying
/debugport=com1 /baudrate=115200) it comes up and s.l.o.w.l.y gets around to
showing a connect message in the debugger. Then nothing.
If I turn on verbose debugging I can see it s.l.o.w.l.y loading – and
unloading – multiple times – assorted modules. After about 20 minutes it
will finally load KSecDD. Then nothing. Ever.
If my partner tries debugging this from another machine she sais it doesn’t
even get that far before it stops. However, if run without the debugger,
the machine runs fine!
I’ve tried to break into the debug session, and tried setting initial
breakpoint. Neither result in a breakpoint. I’ve tried different baudrates
in case the machine is having a serial port problem. Nada.
So. Anyone seen something like this? Even better: have you seen it and
figured out what is going wrong, or what to do about it?
Thanks,
Loren
