Note that this problem can be somewhat controlled by e.g. starting the laptop
without ac, then plugging once booted. Or sometimes by unplugging then
replugging the power cord.
It seems like something is going on with acpi.

could be the memory leak that was fixed recently. Can you try the kernel at
http://people.redhat.com/davej/kernels/Fedora/FC3/ please ?

no change to disk activity. here is a sample of the dmesg output when block_dump
is enabled.

kjournald(471): WRITE block 42616 on dm-0
kjournald(471): WRITE block 42624 on dm-0
kjournald(471): WRITE block 42632 on dm-0
kjournald(471): WRITE block 42640 on dm-0
kjournald(471): WRITE block 42648 on dm-0
kjournald(471): WRITE block 42656 on dm-0
kjournald(471): WRITE block 42664 on dm-0

it runs through blocks like this 8 at a time. but like I said, messing around
with how it's plugged in at bootup and then unplugging - replugging etc makes it
finally quiet.
