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. -- System Information: Debian Release: wheezy/sid APT prefers testing APT policy: (500, 'testing') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 3.1.0-1-amd64 (SMP w/8 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
