While opera is very sensetive to file system corruption, how could a user
application force the system to reboot?

I believe it is a hardware problem. I would expect a disk or ram failure
to cause a segfault, or freeze. Rebooting when the cpu is put under load
sounds like either a heat problem, or a power supply problem, with the
power supply seeming most likely, to me, as I would expect a heat problem
to shut the system down, rather then reboot it.

On older hardware there aren't any over heating protection, which makes it possible to keep on running until the CPU burns or something else happens.

I have had a failing cooling on a PowerPC G4 system, the only way to detect that something was wrong was the random segfaults and compile faults, of course if it had got even hotter, you don't know what could have happen, but replacing the dead fan with a new 40mm fan, it was rock stable again.
On a AMD K7 system I had I did get my CPU up to 125 degrees without it showing any kind of trouble and after replacing the faulty motherboard (it started to supply more volts to the CPU than it should), the system was stable again.

I do agree it's some kind of hardware trouble.
