extremely weird - there simply was no change between -0 and -1 that
could have affected it. If you do this on the -1 kernel:

echo 0 > /proc/sys/kernel/preempt_wakeup_timing
echo 1 > /proc/sys/kernel/debug_direct_keyboard

then you'll get precisely the -0 kernel, bit for bit. (plus the symbol
export fix in rtc.ko, which should have zero relevance to your setup.)

[note that debug_direct_keyboard is dangerous.]

so i believe the explanation has to be something else:

- are you sure the build is correct?

- are you sure it still works with the -0 kernel, maybe the bug is transient?


As i thought the init scripts were my problem. But i have an other question.
I recently started to use NFS. But with the mainline kernel cpu usage is 100%, and when i look in top si shows bewteen 40 and 60% cpu usage. With your kernel si is 0%, but ksoftriqd/0 shows around 38% cpu usage and total cpu usage is around 52%. Is this normal? on my server cpu usage is 2% but it uses a intel network card. My laptop is using a wireless pcmcia card (cisco).
