GaryT might be able to, but ATM, I am stuck because all 3 of these machines 
have to be able to run LinuxCNC, which is very intimately married to 
2.6.32-122-rtai for a kernel.  Compared to the -rt releases kerrnel 
releases, this IS REAL TIME, demanding scheduling with now more than 10 
microsecond responses.

We on the LinuxCNC list are working on that, but I expect it will be 
another month or two before we get all the kernel patches working on a more 
recent kernel.

FWIW, I hate this kernel for desktop work, its a piece of crap for that.  
Runs a gigabyte into swap in a 4 gigabyte machine needing a reboot at 3-5 
day intervals, and kmail gets laggy in 30 hours, needing stopped and 
restarted.  When it gets laggy, its as if an interrupt is being ignored, 
and it may sit there for 2 minutes or more when I click send, while gkrellm 
says the quad core's busiest core is at 2%.

Kmail isn't helped by my having a libsoprano based index cache in the 7.5 
gigabyte range.  My email corpus goes back 11+ years.

Way too late to do anything about it now, but for desktop work, this kernel 
has more bugs than a 10 day old carcass.  Fortunately, they haven't caused 
any great amount of data loss or I would have been loaded for bear long 
ago. ;-)
