I am perfectly happy adding and removing bits of C code and testing the
result - what I lack is the kernel insights. This is a clumsy way to work but
probably the best we have at this stage unless Thomas has the time to
poke around in the interrupt stuff. (Or maybe someone else will volunteer).

BTW - the -p breakage also happens in 2.4.27 UP so it is probably
a red herring. We should get it fixed anyway before it causes more
confusion. I will try the same kernel on a Sun4m machine tomorrow
and see if it also happens there. I have a SS20 with 2 x SM81 as well
as SS5 and SS10. Is there any point in checking this on Sun4c - or
is this still too broken to worry about.
