I have 2 U2's; U2(2x300), U2(2x400). The SMP doesn't matter, though; U2
with 2.6.x will freeze eventually even if a uniprocessor. SMP just lets
it fail more quickly. Problem is believed to be SCSI or Sbus, I think,
but I don't know that anyone is sure. The kernel people have known
about this for well over a year, but no fix.
For more current information, you might ask squash@gentoo.org or
weeve@gentoo.org --- I haven't tried 2.6 on U2 for a while because no
one has claimed to have a fix for this problem. (Gentoo spent a lot of
time on this freeze a few months ago, but no satisfaction. I am sure,
though, that we ruled out SMP as the problem.)
