I just installed Ubuntu Server 14.04.4 LTS on a circa 2009 Dell R900 server. When it boots up and is merely sitting at the prompt awaiting login credentials, I get the message:

Failed to recover vector for irq 44

It occurs around 60 seconds after either a restart or cold boot, and my cursory internet searches don't return anything.

Any help is greatly appreciated!

Thanks!

  • Have you tried updating the BIOS/UEFI? Have you updated all of the packages and rebooted? – QwertyChouskie Mar 4 '16 at 0:02
  • Thanks for the reply. I did just update the BIOS, but I'll go ahead and confirm that the latest packages are installed as well. – Jibberish51 Mar 4 '16 at 0:17
  • Whelp, no such luck. The issue continues to persist after the updates and reboot. I'm looking through dmesg right now, but so far I've not come across anything. I'm looking into this "Debugging IRQ Problems" page now... – Jibberish51 Mar 4 '16 at 0:39

So it turns out that the warning(error?) was coming from one of the servers (5) Ethernet ports. I only need one port anyway, so I disabled ports 2-5 and the error stopped appearing.

I don't know if I would technically call this solved (because it's probably a driver issue), but the problem has been effectively mitigated for my purposes.

Thanks!
