You were talking about the ps table hang when I told you about the rwsem
races. I had the same trouble on my alpha and I reproduced the races
trivially by lanucing:
make MAKE='make -j2' -j2 &
while :; do ps xa ; sleep 1 ; done
After a few seconds ps deadlocked. Try that on the old asm semaphores.
It was 100% reproducible, and after I rewrote the rwsemaphores the
deadlock gone away completly.
Your X hanging in R state is completly unrelated to the rwsem ps table
hang problem as far I can tell.

If you can reproduce without starting X I will be interested in fixing
the hang. Maybe you have a graphics card with a fb driver that doesn't
need VESA that maybe works on the alpha, then you could run X without
privilegies. (btw, in theory we could make the VESA thing working as
well using the x86 emulator in SRM but nobody attempted to implement
that yet)
