So, what is the interrupt service routine doing that it should not
be doing?
o Are you attempting to access paged RAM?
o Are you accessing anything that sleeps?
o Are you enabling interrupts without protecting against
re-entry first?
o Etc.
Your ISR must be doing something that it should not be doing in
order to get this kind of error.

I was going to compile a list of innovations that could be
attributed to Microsoft. Once I realized that Ctrl-Alt-Del
was handled in the BIOS, I found that there aren't any.
