I've applied the attached patch to linux-image-2.6.31-16-generic and am running the patched kernel since late last night. I do see the hrtimer messages but with much lower values and even going down a few times (3375->1500 and 5062->3375):
[ 3304.175297] hrtimer: interrupt too slow, forcing clock min delta to 1500 ns [ 3304.319296] hrtimer: interrupt too slow, forcing clock min delta to 2250 ns [ 3662.181424] hrtimer: interrupt too slow, forcing clock min delta to 3375 ns [ 3674.120250] hrtimer: interrupt too slow, forcing clock min delta to 1500 ns [ 4967.256258] hrtimer: interrupt too slow, forcing clock min delta to 2250 ns [ 5667.966180] hrtimer: interrupt too slow, forcing clock min delta to 5062 ns [ 7238.413947] hrtimer: interrupt too slow, forcing clock min delta to 3375 ns [ 9633.922211] hrtimer: interrupt too slow, forcing clock min delta to 5062 ns [11509.242590] hrtimer: interrupt too slow, forcing clock min delta to 7593 ns [17762.000426] hrtimer: interrupt too slow, forcing clock min delta to 7593 ns [18016.880026] hrtimer: interrupt too slow, forcing clock min delta to 11389 ns My system is now still very responsive, which never happened before after a night of rsync backup runs. I'll keep it running for a couple of days and report back ** Attachment added: "hrtimer patch from the url in the original message" http://launchpadlibrarian.net/37444161/hrtimer.patch -- after kernel message hrtimer: interrupt too slow.... the kvm guest becomes slow [possible solution found!] https://bugs.launchpad.net/bugs/503138 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
