Hi, I have been running SMP on a dual Pentium for almost a year now.
Works great! I just recently purchased a Micronics W6-LI motherboard with
dual PPro 166s. After installing everything, I built an SMP kernel. I
rebooted with it, and after it had probed all of the devices (right before
it would normally mount the root fs), it just kind of sat there. I
thought it was hung, but it still responded to caps lock/num lock/scroll
lock. Also, when I pressed ctrl-alt-del, it printed "Rebooting...", so
the machine wasn't hung. Has anyone else seen this recently? The weird
thing is, my dual Pentium machine does not exhibit this behavior. This
was with sources built from approx. 3AM CST 4-18-98. Thanks.
BTW, here is a dmesg output:
