Good questions, and beyond my ken. "idle=nomwait" did not prevent my system from rebooting while I was away. (I don't know if reboots and freezes are separate problems?) My BIOS doesn't expose anything like "typical current idle", and I have no way to upgrade it since the upgrade tools require Windows.

Is there a guide out there for dummies like me to be able to collect kernel output from these reboots? (Does the kernel even get a chance to do/report anything? Would a report even be helpful to kernel hackers in figuring out more workarounds?) If I can contribute anything plausibly-constructive, I'd love to.

Otherwise, I use and need this machine, so I'll probably just keep treating the symptoms by keeping it busy. (Which I suppose is another software workaround. ;^)
