Well, about 2.2.12 it's a lot more stable to me that any of the previous 2.2.x,
but:
Sep 20 01:21:26 quartz kernel: unexpected IRQ vector 77 on CPU#1!
Sep 21 16:09:31 quartz kernel: unexpected IRQ vector 77 on CPU#1!
^ Spurious messages, no effects, everything continued to run ok.
Now a log of a lockup:

I was using X, and suddenly my monitor went off, when I say off, I can say OFF,
no black, off, vesa extensions, or no signal from the card, I don't know, but
the box was up and the monitor off, the keyboard still worked but the monitor
didn't come up, also the network only repond to pings, telnet and so on was also
gone.
SysRQ-Sync,Umount,reBoot Worked...
And for 2.3.18:

This time X closed and (I'm using gdm) reopen with no major effects.
And another:

After this the CPU1 stops working, now there are some cat /proc/interrupts, as
everyone can see the CPU1 didn't process interrupts anymore since then.

And when I boot 2.3.18 my modem /dev/ttyS1 gets stuck with the send and receive
leds on, and I must do and echo atz >/dev/ttyS1, after this it works ok
(pppd-2.3.9)
Well I was net-disconnected a long time, so thanks for the replys to the FPU
question (I meant two threads, two cpus), and if someone needs more info feel
free to mail me.
