Except that I need to be booted from the new kernel just to do the
upgrade.  Once the thermal condition is tripped, the machine becomes
virtually useless.

So I guess I will see if the latest Ubuntu release can boot up
correctly and then try to upgrade or reinstall.  If not, I may need to
move the hard drive into another machine and try to upgrade the kernel
there.  Uggh.

Thanks,

Russ
