When i close the laptop screen and the laptop sleeps and i wake it up again, the ACPI interrupts shoot up to 5k+/sec and one of the kworker threads uses close to 100% of one of the cpu's. $ uname -a Linux pieters-laptop 2.6.38-8-generic #41-Ubuntu SMP Tue Apr 5 19:30:49 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/717919 Title: ACPI + kworker high interrupts. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
