At the moment ia64 kernels on -current panic in the pmap code. I'd like to get
a backtrace in ddb, but I can't seem to be able to send input to the console.
I was curious if that worked at all or is known to be broken. I also recall
Dough saying that ski engaged in some Linux stupidness with respect to the
tty's that he had to work around. Unfortunately, I can't seem to find an
e-mail with the actual workaround in it, so I'd appreciate any pointers people
have. Also, I've noticed that once I start the kernel going, ski is basically
unresponsive after the kernel panics. None of the windows update if I move
them around, no mouse events, etc. Also, if anyone knows how to fix this panic
(dmesg below) that would be great as well. :)
