I have some new hardware that locks up a lot with Ascii. Sometimes it
happens on its own, other times it seems it can be triggered by going to
the console (ctrl-alt-f1 for example) and back to the X session
(ctrl-alt-f7). Any suggestions about how to diagnose or fix or work
around this? I'm not a hardware person at all.
Below is an excerpt from kern.log capturing such a lockup which happened
at 14 past the hour. The next entries, not shown, pertain to a forced
cold boot.
