(Compiling kernel with make -j2, updating huge RedHat packages with rpm -U, playing Quake3 (r_smp feature enabled by default)) The kernel also returns some data, but except the processor number that locks up (0, i.e. not the boot-processor on this system), I could not find any consequent values, so I guess it is of no use. After the report, the system _seems_ to continue running on one processor (keyboard interrupts are handled, proven by my CAPS-lock-crash-check-led), though the system console is unusable (virtual console switching is possible, though logging in or typing commands is inpossible). A magic SysRQ followed by the hardware reset button is all there is left. 2.3.99-non-SMP runs fine, as does 2.2.14 SMP (besides the lack of decent motherboard support, causing some interrupt problems with MPS 1.4 enabled in BIOS). Also MS Windows 2000 has run for a long time on this system, so hardware problems are unlikely.
