I have a Tyan Titan Pro motherboard, which is dual Pentium Pro 200MHz, but only one CPU on the board (so far). I just built the 2.1.62 kernel on it (I'm sort of keeping up). As distributed, SMP=1 is set in the Makefile. As the system boots (after device detection, as rc scripts are running), I get these messages here and there...
CPU #0: previous IPI still not cleared after 10mS
From the looks of the code & comments surrounding where this message is printed, this is a relatively bad thing.
This continues after the system is up, but eventually, the whole machine locks with the exception of these messages being repeated at the console. Can't even switch virtual consoles, warm reboot, nothing.
I would have guessed that an SMP kernel should be able to run on a single CPU, only a bit less efficiently, but maybe that's not the case? I haven't seen any discussion of SMP development here, so it it still going on or has it stagnated?
