Re: dual G4 time issues..

So far the main problem I'm seeing with the SMP G4 and smp
2.2.18pre4-ben1 is the system hangs up occasionally in xpmac
rev 10, usually when closing an app or logging out. But I've seen
nearly as many xpmac hangs in 2.2.17pre20-ben1 on a Pismo, but
there I can switch VT's and recover. Whereas, on the SMP G4, VT
switches won't work (USB -vs- ADB/PMU?). But, I can't telnet in
either, so maybe it is a hard hang (though enough is alive that it
pings -- not that that means much). Of course, if I have already
telnet'ed in, it never hangs... Will hopefully have time
to build and give XF86 4.0.x a try in a few days.

Other than that, the other problems are the general non-SMP
Rage128 nits of the 2.2.18 fb backport (character rendering
artifacts and occasional raster flickers that probably
indicate non-optimal mclk/sclk settings).

Currently, I've got the CPU load up in the 1.4-1.6 range with
no impact on GUI responsiveness and XMMS playing a CD digitally
without dropping a beat.

I had reports of pthread-intensive applications having the threads
randomly "hang" when running on the SMP 2.2.x kernel. This happens on PPC
only (works fine with the same kernel on x86) and it's fine on UP.
