Dell C6220 running 12.04 does not reboot correctly

Asked by Luke Tymowski

Hello,

We're building an OpenStack cloud using 12.04 on Dell C6220 servers.

The servers will not reboot. They hang part-way through the startup process. (System fans come on at full speed, in what appears to be the pre BIOS check state, but don't appear to progress any further.)

We have to physically press the button or go in via IPMI and force them off/on to get them back.

Dell says the servers are certified only for RHEL, and once we said we were running Ubuntu, Dell tech support refused to comment any further.

Is anyone running 12.04 successfully on the C6220? Or does anyone have suggestions as to where to start looking for the cause?
(11.04 won't even install.)

thanks,

Luke

If you run:

sudo shutdown -h now

Does it die?

Sorry Andrew - I rewrote the question as I misunderstood the original problem - my co-worker is at the data centre, not me.

Yes, the servers appear to shut down correctly. But they don't reboot (my original question stated that the servers weren't shutting down properly.)

The following kernel parameters were tried:
"reboot=bios
reboot=pci
reboot=acpi
reboot=cold
acpi=off
noapic"

Issuing "sudo shutdown -h now" appears to shut the server down.
On pressing the power button, the server fans come on at full speed, but then progress no further. The same symptoms as when issuing a "sudo shutdown -r now" or "sudo reboot" command.

The server must be shutdown via the power button or DRAC interface before it will start correctly.

Further update:
Booting with "nolapic" allows the server to reboot or shutdown and start again. Is this safe to leave on or is it considered harmful?

It's fine, you just disabled the feature in the BIOS which is causing the issue.

Actually, it's not really fine. Using "nolapic" disables all but 1 CPU. In my cause, my server of 32 CPUs had 31 unavailable.
