This kernel ran "make clean ; make -j32" all night long. It's completed 415
cycles with no apparent problems. Average cycle time is 147.2 seconds.
Minimum is 144, max is 158 ... which all looks very normal.

It's probably a good thing that the unsigned RWSEM_WAITING_BIAS
problem led me to this commit with a problem that showed up during
boot. I'd hate to be bisecting this based on a problem that only shows
up after an unknown number of kernel builds :-)

Still no reports from other architectures? So this still seems to be an
ia64 specific problem. Time to start reading rwsem.c
