Ok, can't help with the rest of your answer, but I'd like to help debug if the
issue is here.
Problem: I can't do anything at db> prompt? Backtrace is doing nothing except
triggering a new register dump (another fault I assume).
Anyway, I'm using:
device card
device pcic
device ep
I started looking around in src/sys/dev/{ep,pccard,pcic}/* for recent changes
that could have caused it, but I soon got lost... :(
What should I try? I can go back to an earlier kernel (via cvs & compile, sadly
I don't have any old working kernel anymore), but I'd have to first understand
how far back I can go without getting out of sync between kernel & world...
Meanwhile, I'll try the latest kernel, and also cardbus to see if the results
are different in any way...
Bye,
Andrea
