FYI: NIC Had LSI Chip (L2A1157) and I have a Nvidia Quadro FX 4800/PCIe/SSE2
graphics card installed.
Seems to be some type of Hardware & IRQ issue.
Problem has been gone for last 2 days.

I can confirm that the problem stopped when I removed my NIC. Now IRQ 16
is only used by my video card.

Title:

I also experience this problem. I've been having it for a while. Logging
out and logging in again temporarily fixes the issue. Affects both KDE
and Gnome. Got this in /var/log/syslog when the problem happened just
now:

I'm having a similar issue in Saucy Salamander. After using my computer
for a while, GUI slows down somewhat, not unusably slow, but animations
are signficantly slower. Even the Window side by side snap animation
shows a little lag, I begin to see the fade effect in icon right click

For the record, I have tried booting with the irqpoll option, does not
help.
Doing echo 'options nvidia NVreg_EnableMSI=1'
/etc/modprobe.d/nvidia.conf as recommended in that post you linked does
apparently not activate MSI for nvidia as intended. There was no file
with that name in that
my /proc/interrupts shows ohci_hcd:usb2, snd_hda_intel, nvidia on the
affected IRQ11. Does that mean I can choose to have either usb, sound,
or a graphics card? I can hardly disable two of those three...
Does anybody know something to do (a command to run or whatever) to
alleviate this error if
I've been running with my firewire module removed for a couple of weeks
now, and have not experienced the slowdown.
Christoph, have you tried the first option mentioned in this post?

Checking my /proc/interrupts, I have a firewire module on IRQ16
alongside the Nvidia driver; I believe this is from my PCI soundcard. So

I updated my machine with the latest 12.04 updates in the past week,
which included some compiz updates (to 0.9.7.8), and the problem is
still occurring.
As mentioned by Christoph, around the time of the latest occurrence I
got an irq 16: nobody cared in syslog:

Today, I got that error even while using Unity2D, so comment #5 has to
be disregarded. :-(
Can someone bump the importance? - Now that avoiding this by switching
to unity2d is impossible, this makes working basically impossible after
an undetermined time in the session.

Another data point: After a workday of using Unity2D instead of Unity, I

I think I'm affectd by the same bug. I foud ou that when the bug is triggered,
I get a message in the syslog about
irq 11: nobody cared. tis only ever happns whnthe bug is triggered
You gota similar thing in curentDmesg, I sspect this could be related to the
bug trigger:
irq 16: nobody cared
Also, I just discovered that instlling thenew nvidia driver from
precise-proposed (295.49) does NOT fix this issue... :-(
Please bump the severity, this consistently makes the system unusable after a
time!
