I upgraded from gentoo-sources-2.6.27-r4 to -r5 a couple of days ago and
got the below error messages in /var/log/messages. Also dovecot was using
100% CPU and could not be killed. This resulted in me having to hard reset
the server. This happened 3 times until I eventually reverted back to -r4
and all was stable again. The config used for both kernels was the same
and it happened after irregular intervals of between 5 hours and 9 hours.

Anyone have any ideas? Things are back to normal now but I will obviously
be wary about my next kernel upgrade.

Just apply the patch to lib/idr.c and things should be fine again (or wait
for stable.10). GregKH is doing an amazing job and it's not his fault, but
nevertheless the rate of changes to -stable has just totally spiralled out
of control.

Thanks very much for the info. I won't worry about doing an upgrade 
until .10. I agree, I think the whole kernel development team is doing a 
wonderful job and this is the first proper hiccup I've had in years. :)


Cheers,
Dave.
