Hi Ingo, Thomas, and the greater linux-rt community,

	I just wanted to let you guys know that our team has a port of
the 21.5-rt20 patch for the 2.6.22 kernel available. [...]

great! We had the upstream -rt port to .22 in the works too, it was just
held up by the hpet breakage - which Thomas managed to fix earlier
today. I've released the 2.6.22.1-rt1 patch to the usual place:

    http://redhat.com/~mingo/realtime-preempt/

Thats awesome, Ingo!  Thanks!  Could you publish a broken out version
as well?  We found it extremely valuable to be able to bisect this
beast while working on the 21-22 port.

we are working on something in this area :) Stay tuned ...

I've just been reviewing these patches and have spotted an error in the
file mm/slob.c at lines 500-501 whereby a non existent variable "c" is
referenced.  The attached patch is a proposed fix to the problem.

Could this explain why 2.6.22.1-rt1 seems to use a lot of swap?  I've been as 
high as 570 megs into swap, currently at 286megs after doing a 
swapoff --a;swapon -a about 8 hours ago.

No.  This problem would have caused the build to fail if slob was
configured.
