Package: linux-image-3.2.0-4-amd64
Severity: normal

Dear Maintainer,

the kernel load of the kernel listed above is too high - we're experiencing
load spikes of 20, 30 and more on a dual-core processor without an indication
of the cause. The CPU usage is low (less than 50% of each core utilized), and
the load jumps from like 2 to 20 in a fraction of a second. This happens on at
least two machines which run KVM. This is probably a load calculation bug only,
because the system is very responsive, even with that huge load.

I have no good recipe to reproduce this - it seems to be related to disk I/O,
but I'm not certain about that.

It sounds very much like issue #674153, as well as
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/985661 or
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/995284

I have no idea which useful information I could attach to this bug; again I
believe this is only a display issue (but which, in turn, breaks things like
system monitoring, and turns any triggers into a blazing storm of error
notifications at the NOC). Thus I also believe that this might be a showstopper
for the wheezy release.

Hi

This bug was filed for a very old kernel or the bug is old itself
without resolution.

If you can reproduce it with

- the current version in unstable/testing
- the latest kernel from backports

please reopen the bug, see https://www.debian.org/Bugs/server-control
for details.

Regards,
Salvatore
