David, This is just a guess.... The main change (that I know of) was in 2.6.24 to support “tickless idle”. I just finished(?) fighting the battle to get the system timer to run reliably (discovering, in the process, a (minor) bug with our SoC ;-\ ). I've a meeting in a few minutes and so no time to write down any details (now), but hopefully Ralf or someone can either fill you in or point (both of us) to some doc. cheers! -blf- -- “How many surrealists does it take to | Brian Foster change a lightbulb?
