I just booted with 2.6.24-17. It appears to solve the problem.
My usual test is to start copying large files (to an external disk),
and try to show/hide Yakuake. Which to my surprise, doesn't freeze mid
way through the screen.
Making multiple threads read from /dev/zero (see below), with atop
reporting disk busy at 99%, I still have a responsive system.
Took this from an earlier email from Thomas Pi:
dd if=/dev/zero of=test1 bs=4k count=250000 & \
dd if=/dev/zero of=test2 bs=4k count=250000 & \
dd if=/dev/zero of=test3 bs=4k count=250000 & \
dd if=/dev/zero of=test4 bs=4k count=250000 & \
dd if=/dev/zero of=test5 bs=4k count=250000 & \
dd if=/dev/zero of=test6 bs=4k count=250000 & \
dd if=/dev/zero of=test7 bs=4k count=250000 & \
dd if=/dev/zero of=test8 bs=4k count=250000 &
