Hi. I'm currently running NetBSD and am having a problem with it. I'd
like to know whether there's still room in John Hawkinson's IAP NetBSD class,
and when it meets (if it hasn't met already). I'd like to learn more about
NetBSD, including how to install a third party driver and SCSI peripherals and
how to solve the problem that currently causes my machine to crash at the
worst times.
My problem right now is as follows: Once I finally got my network card
to work, I noticed that the machine would freeze unexpectedly in X
during periods of
high disk and mouse activity. Sometimes, the machine will freeze while the
hard disk is being accessed, resulting in the hard disk activity light to glow
steadily. I imagine that this is not good.
I suspected an IRQ conflict, especially since I
don't have this problem in ttymode sessions and my current "fix" is to turn
the mouse upside down in X and use it as little as possible. After spending
a long time, I managed to prepare the machine to crash in X while I switched to
ttymode. I then got an error message:
kernal: non-maskable interrupt trap, code=0
stopped at _sendsig+0x9c:movl % ecx, 0xffffffc4(%ebp)
I have been able to reproduce this message.
I've already tried reconfiguring mouse and video protocols in several
ways. I took out my sound card (which eats up 3 IRQs by itself) and got the
same problem.
My mouse is on com1 irq3. The other irq-looking things I've seen at
startup are as follows:
w 0 at irq 4
com1 irq 3 (the mouse)
lpt0 irq 14
isa0 irq 10
isa0 irq 1
I hope you can help, and I hope the class is still available.
Thanks,
Dan Kamalic
