I had the same problem awhile back on this system and couldn't find the solution this time around, but stumbled across it - I think it's the same issue and the aptitude upgrade last night brought it back: ondemand

The symptom is after a reboot and tailing logfiles and such, there's not indication why the system hangs up completely - it doesn't take long, more than a minute apparently.

Disabling the ondemand init script appears to be the fix. Looking at /etc/init.d/ondemand it has a 60 second delay so that explains the delay.

I manually moved /etc/rc{2,3,4,5}.d/S99ondemand to K01ondemand - I also removed Default-Start: 2 3 4 5 from the preamble of /etc/init.d/ondemand and ran "update-rc.d ondemand default". I suspect the recent upgrade "fixed" the old init script I had removed or changed or whatever.


I've attached a dmesg from the server. also
cat /etc/debian_version

I just came across this exact same problem with my VIA Nano installation. Using your clue about the ondemand script, I ran some tests and got more information about of the problem.

I have filed BUG#805205 (https://bugs.launchpad.net/ubuntu/+source/linux-meta/+bug/805205) with my findings.

I finally solved this hanging problem. I needed a BIOS update.
