Those are the same symptoms that I experienced. Only difference is that I wasn't able to connect via SSH (the box is running Samba, BIND9, DHCP3 and SSH, and a few other stuff, virtualbox for one).
Ctrl+Alt+Del to force a reboot was recognized and halted all the processes and rebooted the machine. Do those Dell servers run RAID? The only thing I can think of is that on my server, I've got a 3 disk RAID-5 array (using a RocketRAID 2640X1 controller: http://www .highpoint-tech.com/usa/bios_rr2640.htm) that I need to build the drivers from source after each kernel upgrade - which had an entry in fstab. The main OS drive was a 320GB WD Caviar Blue, which wasn't set up for RAID. What about Virtualbox? I had Virtualbox installed from the karmic repos over at Virtualbox.org. Just reaching at straws here. Also: I ended up doing a clean install of Lucid Server x64 and running apt-get dist-upgrade to get the new kernel before installing all the services. The upgrade went fine and I was able to get to a prompt after rebooting. After installing all the services, and rebooting, the RAID controller was recognized and everything loaded up without hanging. I am quite puzzled. -- kernel 2.6.32-32 makes machine hang during boot https://bugs.launchpad.net/bugs/576001 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
