Message-ID: <4DE4A30A.9010207@gmail.com> (raw)
Yesterday, I compiled the new kernel 3.0rc1 from git, but I never
successed to go over the point: "Removing old temporary files".
Pressing control-c let me boot on, but the pc was the complete time on
very high load. It took me minutes, just to reach the tty login - and
again minutes after login in, that I had my shell and a prompt to enter
something. The load was at that time beyond 10.
Now in my /var/log/messages, I found the following warning - and because
it happens when "removing" temporary/old files, that might be why the
computer has so much trouble:
