Even if it seems that select is buggy, the kernel is safe and these
messages could be safely ignored. Due the fact the kernel is safe you are
seeing the schedule_timeout() error messages ;-).

Probably it would be better to do the check also in select() and in
nanosleep() just to avoid malicious log-flooding attacks.

I just added a superflous check in select poll and nanosleep after the
time->jiffies conversions to avoid userspace to generate printk() and
left the schedule_timeout() message to real kernel errors. I' ll sync/forward
these not urgent fixes to Linus when the stall bug will be fixed too.

The fixes are in ftp://e-mind.com/pub/linux/kernel-patches/arca-20..

Thanks for the report Simon!
