[ros-kernel] Finally have good stack trace on crash I'm experiencing...

[Royce M. I. <ro...@ev...>]

Okay,

I finally had a little bit of time to play around with ReactOS again,
so I downloaded the latest CVS, compiled with DBG=1, and it's still
crashing, but now, at least, I have been able to produce a valid
stack trace. I took the screen dump, and did an addr2line on each
entry. Here are my results:

--------------------------------------------------------------------------------

Here is the line that's crashing:

portio.c:68 :

   __asm__ __volatile__ ("cld ; rep ; insw"
                         : "=D" (Buffer), "=c" (Count) 
                         : "d" (Port),"0" (Buffer),"1" (Count));

Here's my results on the stack trace:
