Speaking of which.. what's with powertop on 2.6.24 ???
It's gone from 100-200 wakeups/sec to 20000 wakeups/sec !!!!!!!
ho hum.. Lenovo T61?
I have some reports that that happens once in a while (but it's not
limited to .24 and it's also real, it's not a powertop bug but it
actually is waking up that much)..
..

No, it's my hefty Dell Inspiron 9400.

And I just figured out the powertop: it needed the kernel timers
patch from the powertop site that was originally for 2.6.21..
...

Dagnabbit.. it's done it again.. went from 100-200 wakeups/sec
back up to 20000+ wakeups/sec. This time *with* the powertop patches in place.

What is the status with an unpatched 2.6.23?
..

More wakeups than without patching, but still on the order of hundreds
of wakeups/sec; nowhere near the 20000+ wakeups/sec range when it goes wonky.

Please send the output of "dmesg -s 1000000" for both 2.6.23 and 2.6.24.
..

Okay, I'll do a couple of reboots and collect that info for private email,
and maybe post a diff of the two here.

Cheers
