David: If you want to get a head start tackling this, try this idea (it's what
I'm going to do when I get my lazy self back into gear). Start with a 2.6.10
mips-kernel to use n32. This will give you a somewhat usable kernel with a
somewhat usable n32 userland. The annoying pthreads bug doesn't appear in this
Now, starting from 2.6.12-rc1 (the next kernel rev checked into lmo cvs, they
skipped 2.6.11), do a checkout of _each day_ of linux-mips CVS, build a kernel,
and try it. Keep repeating until you find the first day the pthreads bug geoman
mentions first appears. Once we know this day, we can take a look at all the
CVS commits made that day and likely find the culprit patch that h0rked us.
Once found, maybe we can get some attention drawn to it on the linux-mips list
and thus get it fixed.
As for the shmem thing, good luck, heh. We've been trying to figure that one
out for months. hdparm is a program that will generate it every time. strace
too. Maybe one of those programs can be used as a test case to narrow down and
squish the shmem bug as well.
