[Bug 1084264] Re: Kernel 3.2.0-33 Introduces Ridiculous / Impossible Load Averages
I can no longer replicate this using the 3.2.0-54 kernel. I'm going to assume one of the intermediate versions fixed the issue. ** Changed in: linux (Ubuntu) Status: Incomplete => Fix Released -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1084264 Title: Kernel 3.2.0-33 Introduces Ridiculous / Impossible Load Averages To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1084264/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1055222] Re: Kernel panic on reboot after sched_autogroup_enabled disabled
This broke startup and shutdown on all our HP DL380 G7's and our Dell r710s. We didn't use the setting on other servers, so can't confirm. We're wondering if restarting a service recently caused a kernel panic due to this bug as well, but can't reproduce reliably. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1055222 Title: Kernel panic on reboot after sched_autogroup_enabled disabled To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1055222/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Upon further investigation, this seems to affect every Ubuntu 3.2 kernel. We've tested -24, -31, -33, and the upcoming -34. All exhibit impossible load swings. Only using 3.4 fixes this. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1084264 Title: Kernel 3.2.0-33 Introduces Ridiculous / Impossible Load Averages To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1084264/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1084264] Re: Kernel 3.2.0-33 Introduces Ridiculous / Impossible Load Averages
Unfortunately DRBD 8.4.2 will not compile against the 3.7rc7 kernel, nor will iomemory-vsl, two vendor source-based modules that seem to rely on deprecated kernel API calls. However, 3.4.20 from Quantal does not exhibit this behavior. Again, this is fixed by installing 3.4.20 on 12.04 LTS. ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed ** Tags added: kernel-fixed-upstream -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1084264 Title: Kernel 3.2.0-33 Introduces Ridiculous / Impossible Load Averages To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1084264/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

System is behind a firewall and can not contact Ubuntu servers, and is operating from a repository clone. apport-cli seems to think the linux- image-3.2.0-33-generic package is not from Ubuntu. I'll collect any necessary information manually if requested. ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1084264 Title: Kernel 3.2.0-33 Introduces Ridiculous / Impossible Load Averages To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1084264/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1084264] [NEW] Kernel 3.2.0-33 Introduces Ridiculous / Impossible Load Averages
Public bug reported:
After upgrading to the 3.2.0-33 kernel, our load averages have been
very, very odd. Here is a sample sar -q line:
15:05:02 runq-sz plist-sz ldavg-1 ldavg-5 ldavg-15 blocked
15:05:212 322 44.02 12.51 14.08 1
A run queue size of 2, with a load average of 44? So I wrote a script to
track run queue and uninterruptable sleep, since both contribute to load
average. Script is attached. Sample output during a run:
Stat Time Run+Sleep Load Avg
2012-11-28 15:47:53 2 71.54
2012-11-28 15:47:54 1 71.54
2012-11-28 15:47:55 1 71.54
2012-11-28 15:47:56 1 71.54
2012-11-28 15:47:57 1 71.54
2012-11-28 15:47:58 1 65.81
This behavior is not observed with kernel 3.2.0-31.
Problem can be reproduced with a basic pgbench test to simulate busy
state, but only seems to occur during rapid process cycling. An easy
simulation:
for x in {1..100}; do
pgbench -T 5 -j 2 -c 2 pgbench
sleep 1
done
Test may need to run for several minutes to trigger load spike. It will
look similar to this:
Stat Time Run+Sleep Load Avg
2012-11-28 16:01:17 3 10.37
2012-11-28 16:01:18 3 9.54
2012-11-28 16:01:19 3 9.54
2012-11-28 16:01:20 2 9.54
2012-11-28 16:01:21 5 9.54
2012-11-28 16:01:22 3 9.54

[Bug 501715] Re: ureadahead doesn't free memory after profile
This is insidious. I was wondering where 500MB of my memory went, and ps, top, etc, didn't report who stole it. I upgraded some packages to make sure it wasn't a memory leak and rebooted. Unfortunately the package upgrade either invalidated the ureadahead pack, or reset it or something, because after a fresh reboot with just GDM running, free looked like this: total used free sharedbuffers cached Mem: 2016984 7618441255110 0988 144416 -/+ buffers/cache: 6075801409404 Swap: 2104472 02104472 Upgrading to Karmic proposed packages did *not* fix this. Rebooting twice in a row without logging in, did. Now I guess Ubuntu is worse than Windows in this respect, since it takes *two* consecutive reboots to fix a problematic system instead of one.
