powertop gives me 4 suggestions - and i accept all of them. After accepting the suggestions and closing down powertop i have not had any freezes. So my guess is that one of those 4 things makes it freeze in default configuration. But which one? - i don't know enough about powertop and kernel to guess. I will over the next couple of days try to disable one by one and see if i can figure it out.
Suggestion: increase the VM dirty writeback time from 5,00 to 15 seconds with: echo 1500 > /proc/sys/vm/dirty_writeback_centisecs This wakes the disk up less frequenty for background VM activity Q - Quit R - Refresh W - Increase Writeback time Suggestion: Enable SATA ALPM link power management via: echo min_power > /sys/class/scsi_host/host0/link_power_management_policy or press the S key. Q - Quit R - Refresh S - SATA Link Power Management Suggestion: Disable 'hal' from polling your cdrom with: hal-disable-polling --device /dev/cdrom 'hal' is the component that auto-opens a window if you plug in a CD but disables SATA power saving from kicking in. Q - Quit R - Refresh K - kill hald-addon-storage Suggestion: Disable the unused bluetooth interface with the following command: hciconfig hci0 down ; rmmod hci_usb Bluetooth is a radio and consumes quite some power, and keeps USB busy as well. Q - Quit R - Refresh B - Turn Bluetooth off -- Ubuntu 8.04 Freezes https://bugs.launchpad.net/bugs/228633 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
