Hi !-
I have sent a MIPS patch to Ingo and Thomas just yesterday to support
realtime on MIPS in 2.6.17 and using the 2.6.17-rt1 patch. I have got
that patch working on Broadcom SWARM board (32-bit UP/SMP).
Try this out and let me know. I have run some stability tests on this
kernel and have not noticed any hangs so far. So, it will be interesting
to flush out any bugs.
Thanks
Manish Lachwani

That problem actually went away with 2.6.16. All the others remained
unfortunately. (I was not that concerned about that one ... I can
avoid it just by not sending a sysrq ;-). I posted it though since I
did actually have output with that hang).

I will post the other changes soon. (I am not at the office where I
am working on this yet this morning). I will also try 2.6.17.
Thanks.
