I just upgraded my Ubuntu server from 9.04 to 9.10 and after about 10 minutes it locks up. It won't respond to ping, can't ssh in and the terminal doesn't accept keyboard input. It does not have X installed. I then reformatted and installed it from scratch with the same results. There are two hard drives, the first is for the OS and the second is for media. The second has not changed, it is an ext3 formatted drive with one partition.
I stopped random services (samba, ushare, transmission-daemon) to see if they were causing the issue, but it still locked up. I did a watch "dmesg|tail" until it locked up, but I didn't see anything.
How can I troubleshoot this further? I don't want to downgrade.
Machine specs:
Dell Dimension 3000
Pentium 4 @3GHz

I had the same issue with Ubuntu Server 9.10 (headless setup, Intel graphics). Adding nomodeset option to /etc/default/grub worked fine for me. Don't forget to run
after all.
