I understand that other arches need to stay at 2.4 for various reasons.
Hopefully those issues will be fixed so that this situation doesn't stay
that way for much longer.
You're not the only one hoping they're fixed soon :)
I am supprised that Sparc64 is stuck with 2.4, as the main kernel
developers of that tree work on 2.6 everyday. As for mips, I thought
the recent (few kernel versions ago) merge brought you all up to speed?
Anything that I can do to help this, please let me know.
Yeah, it's a bit surprising really. It depends heavily on the machine, and upon
certain options in the machine. I run a Blade 100 with 1 IDE and 1 SCSI drive,
and 2.6.7 is the last "good" kernel for me. 2.6.8.1 -> early 2.6.11 apparently
had something nasty that buggered up the scsi subsystem to the point where heavy
disk activity brought a system to its knees in minutes. I haven't tested
anything newer as I usually wait for a grsec release before building a new
kernel for my non-mips systems (and they haven't released anything for 2.6.12 yet).
The current issue going on, I haven't followed too closely, but it appears to
cause various issues on several machines. In one case, a Netra 1450 with 4x
CPUs keels over on 2.6.1 and up within several minutes of doing anything on it.
squash is going to go back and test all the 2.5.x kernels to try and find the
point at which it all started happening.
The thread regarding all of this (and has davem participating in) started here:

As for mips, the only system gentoo-supported that still has a link to 2.4 are
the old IP22 (SGI Indy/SGI Indigo2 R4x00) systems. When I run ~2.6.10 on it, I
can usually hang the box after a couple hours of building something (like
glibc), whereas geoman can run his Indy for days on 2.6.x w/o incident. Likely,
there's probably some tricky bugs left that hinge on a specific CPU revision,
and I just happen to have the one revision that causes the bug. I just haven't
fired the system up and really taken a good look at it.
