Hi,

This morning I resumed my laptop from hibernate and noticed the following trace that occurred a minute or so after the resume:

Jul  6 09:45:01 localhost kernel: irq 16: nobody cared (try booting with the "irqpoll" option)
Jul  6 09:45:01 localhost kernel: Pid: 0, comm: swapper Not tainted 2.6.31-rc2-pae #83

Jul  6 09:45:01 localhost kernel: Disabling IRQ #16

I did not reboot but later on in the day I also returned to a blank screen instead of a screen saver - not sure if could be related to the above. I could get 
back to a text display after using alt-sysrq-e, but decided to reboot since I had in any case lost my X session.

No such issues on 2.6.30, this is running Fedora 11.

Regards,
Niel
