Bug Description
I've recently started getting the following messages in /var/log/syslog about every minutes. Googled "Missed a PM interrupt" but no useful results have come up.
Except that sudo is somewhat slower than it was used to be, nothing seems wrong with my server for now. Can I ignore this messages? Maybe this issue is related with Bug 38632 - IRQ Nobody Cared on Sandybridge Additional Ethernet Card (https:/

From the logs (CurrentDmesg.txt and WifiSyslog.txt) it looks like this is an upstreams issue. There's a bug report here:
https:/ /bugzilla. kernel. org/show_ bug.cgi? id=42907
And some discussion here:
https:/ /lkml.org/ lkml/2011/ 9/2/342
Unfortunately, the logs are not conclusive as they are not complete: the 'Tainted' field contains a 'W', which means a warning has previously been issued by the kernel. Would you be able to attach a complete dmesg log next time you see this issue? In the meantime, I'm setting the status of the bug to 'Incomplete'. Please change it to 'Confirmed' again once you have a full dmesg.
Also, this seems to be caused when resuming from suspend/ hibernation. Can you confirm this?
