Description of problem: After resuming from suspend mode, my CPU is constantly 65-70% busy with a kworker/0:1 thread. Also the value of /sys/firmware/acpi/interrupts/gpe_all is increasing very quickly. Both don't happen after a fresh boot. Version-Release number of selected component (if applicable): I'm running an unmodified kernel 2.6.38-0.rc7.git2.3.fc16.x86_64 from Rawhide. How reproducible: Every time my system resumes from standby. Steps to Reproduce: 1. Suspend the computer using the GNOME Shell menu. 2. Put the computer back on (by pressing the power button here). Actual results: An active kworker thread keeps running, and the value of gpe_all is increasing quickly. Expected results: Low CPU usage when the pc isn't doing anything, a constant value of gpe_all. Additional info: I'm actually not sure what it all means. I had a similar problem with 2.6.36 versions of the kernel, but then also when I didn't use the suspend mode at all. This was discussed and fixed in Bug 638912.
Should be fixed in 2.6.38.2-8.fc15
kernel-2.6.38.2-8.fc15 has been submitted as an update for Fedora 15. https://admin.fedoraproject.org/updates/kernel-2.6.38.2-8.fc15
kernel-2.6.38.2-8.fc15 has been pushed to the Fedora 15 stable repository. If problems still persist, please make note of it in this bug report.
the kworker problems is still stealing 85% cpu AND interfering both keyboard and mouse input NOT only causing delays in version 2.6.40.4-5.fc15.x86_64.
Fedora 16, 3.1.9-1.fc16.x86_64 Intel(R) Core(TM) i7-2630QM CPU @ 2.00GHz After wake up kworker/0:2 consumes about 60% cpu.
