Lost interrupts, surely: the clock was many hours behind actual time (actually a few days after the last long weekend). Broken hardware, highly unlikely. (I'll try to reproduce it on another identical machine.)
With my minimal .config, all is well. With FC's .config (perhaps with a few subsystems - production & experimental, like Bluetooth, i2c etc.), however, the problem is reproduceable. Naturally, FC's .config loads many kernel drivers (538 symbols on my minimal .config vs 1800+ on FC5's). Because there are way too many symbols, I thought someone would be quick to point out which one of those would be to blame :-) by looking thro those processes.
And oh, eventually machine recovers (minutes sometimes, hours other times), & it runs as if nothing happend, as long as you're not quick to power button. Sure, you can't login, or you can't execute commands, if you managed to login etc. But patience does bring the machine back every time :-).
(On request I'd gladly provide my minimal .config & FC5's.)
I think I should remove those symbols one at a time to narrow it down. That would take many days though. But it'll be worth a try, if there's no other way.
Thanks
