OK I just found a way to drop the CPU load without stopping udev. The trouble is I cannot confirm that this method will work because I was not able to re-duplicate it before posting, so your mileage might vary. Here is what I did:
# hal-disable-polling --device /dev/sr0 It printed a bunch of messages that got lost because I did a top to check the load and was surprised to find that the CPU load dropped instantaneously!! The funny thing (to me) is if HAL was dropped from Lucid and if I did a fresh install of Lucid so the /etc scripts should not have had any initialization of HAL, why then should any HAL stuff be running?? I sometimes saw: hal-addon-stor running but never thought of stopping it until now. What is even more strange to me is when I do the following right now: # ps ax|grep hal I see: 1862 ? Ssl 0:00 /usr/sbin/hald 1863 ? S 0:00 hald-runner 1899 ? S 0:00 hald-addon-input: Listening on /dev/input/event5 /dev/input/event10 /dev/input/event7 /dev/input/event6 /dev/input/event2 /dev/input/event1 /dev/input/event9 /dev/input/event3 /dev/input/event0 1902 ? S 0:00 /usr/lib/hal/hald-addon-rfkill-killswitch 1903 ? S 0:00 /usr/lib/hal/hald-addon-leds 1913 ? S 0:00 /usr/lib/hal/hald-addon-generic-backlight 1921 ? S 0:00 hald-addon-storage: no polling on /dev/sr0 because it is explicitly disabled 1926 ? S 0:00 /usr/lib/hal/hald-addon-cpufreq 1927 ? S 0:00 hald-addon-acpi: listening on acpid socket /var/run/acpid.socket 3650 pts/1 S+ 0:00 grep hal So what's going on? Has HAL truly been disabled or what? Any serious explanation of what happened to solve the problem for me would be much appreciated. The load kind of instantly dropped and do not come back after restarting my laptop, which is a good thing in my book. :) -- CD-ROM polling on some Optiarc drives causes high CPU usage https://bugs.launchpad.net/bugs/379780 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
