[mythtv-users] Crash on network transfer?

So I tried this while doing the transfer, had my box sitting on the terminal
and couldn't get any of those keys to work.  The lights aren't flashing on
my keyboard, but unfortunately none of commands below seemed to have any

When the machine froze up, some output automatically went to the screen
saying there was a double fault.  None of this went to /var/log/messages and
I'm not sure if there's another place errors like this would go.

The only two devices sharing an interrupt are my SB Live card and my Nvidia
video card.  I don't know if this could be related, but other devices are
all on their own IRQ.

Thanks again for the help and suggestions.

How did it crash. Do the keyboard lights flash?

Change /etc/sysctl.conf, set kernel.sysreq to with this line:

	kernel.sysreq = 1

this will set sysreq on during reboots. Do this to turn it on now without a

	echo 1 > /proc/sys/kernel/sysreq

Next time it happens try pressing one of these keys to see what is
happening. (I use p and t often)
