This is a follow-up to my previous posting about the freeze/lockup
problem with 7.10.  I'm the person with a Dell D810 who regularly
encounters this problem.  Because Tim Fuchs felt this bug might be due
to the wireless driver, I hung an ethernet cable down my stairwell and
ifconfig-ed my wireless interface down.  About 20 minutes later, the
system locked up hard, just as it has before.  When it locks up, the
cursor will move around the screen, but the system is completely
unresponsive to mouse clicks or keyboard typing.  So, it seems like this
bug, or at least the bug my D810 is encountering, is NOT related to the
wireless driver.

I guess I should repeat my previous question: does anyone know if there
is a way to force ubuntu to drop a kernel core, when the system is
locked up such that linux won't respond to anything typed at the
keyboard?  I'm wondering if there is some way to force it into BIOS, and
then if there is something that can be typed at BIOS, that would cause a
core to be dropped.
