pls help: Context Switching in Irix doesn't work

[Angus Y. Montgomery]

  We are trying to port some code that does run on other MIPS
platforms to the Iris.  The assembler that does the context switching
seems to be where the problem lies.
  I have been told that other people have had this problem, and overcame
it by "leaving extra space on the stack for interrupts".

  If anyone feels at all intelligent when confronted by this stuff, or
knows of anyone that fits this description, please get me in touch with
you/them...

  The assembler code and a bit of doco for it is available for anyone eager
to tackle it!  If you think i should post it, then say it.

  thanx.
