It is udisksd reporting 'Error performing housekeeping for drive' 'Error updating SMART data: sk_disk_check_sleep_mode: Operation not supported (udisks-error-quark, 0)'
How does the Kernel's polling work? Shouldn't udisks be able to tell the Kernel not to poll a drive then? If that is possible it's probably just a feature request instead of a bug. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/379780 Title: CD-ROM polling on some Optiarc drives causes high CPU usage Status in Linux: Confirmed Status in udisks: Fix Released Status in linux package in Ubuntu: Invalid Status in udisks package in Ubuntu: Fix Released Bug description: Binary package hint: udev Before I upgraded the udev version of jaunty from 141-1 to 141-1.1, top reported about 2% total cpu usage when idle. After the update, it rarely drops below 35%. Though top lists udevd among the more cpu hungry processes, it is only listed with about 3%, while system (in line 3) almost never drops below 20%. I am using the amd64 version of Xubuntu 9.04 on a Acer Extensa 5230 laptop with a 2 GHz Intel Celeron processor, and I have my root, home and swap partitions encrypted with luks. I did a fresh install and installed nothing but the software updates.
