This is a problem with U2+kernel-2.6.x generally. Unfortunately, I
have no suggestions nor do I have a solution. I just grit my teeth and
stay with the kernel-2.4.x series, which are completely stable on U2,
so far as I can tell.
What is your U2 configuration ? I have only one U2 and I cannot test on
this station because it's a mail server :-( In fact, I think it should
be interesting to know if this trouble come from SMP, ESP or Sbus
support. It is impossible to build a kernel with debug information (it
does not boot due to a address not aligned...), but I have tested the
same kernel on a U1E (with the same ESP chip and two additional
HappyMeal Ethernet cards on Sbus slots). It perfectly works. Can you try
a 2.6 on U2 without SMP support ?

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.
I have seen your post on gentoo-sparc mailing list. I have made some
search to find more posts wihtout any success. I'm not sure this trouble
was known, I haven't seen any post on kernel mailing list.
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.
I have seen some posts about ESP troubles. For me, all ESP troubles
were fixed on sparc64.
For more current information, you might ask squash@xxxxxxxxxx or
weeve@xxxxxxxxxx --- 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.)
I have seen you have tried to build a 2.6 kernel with gcc-3.3 and 3.4.
I have tried 4.0 and 4.1 with the same result.
