My Ubuntu PC at home occasionally has suffered with a rather annoying issue, whether the CPU runs at pretty much 100%, and the temperature to rise causing the BIOS to make an awful and incessant beeping sound!
Well tonight it just got too much for me, and I decided it was time to look into the cause.
A quick google search had me run “top” from a command line, which showed that a process by the name of “kacpi_notify” was consuming all the available CPU! So another search lead me to this page on the fantastic ubuntuforums.org, with a possible solution.
So just for the record, I applied the following changes:
sudo gedit /boot/grub/menu.lst
Then modified the line:
kernel /boot/vmlinuz-2.6.24-16-386 root=UUID=d17c8a59-107b-4454-9369-f24aaa7776f0 ro quiet splash
kernel /boot/vmlinuz-2.6.24-16-386 root=UUID=d17c8a59-107b-4454-9369-f24aaa7776f0 ro acpi=off apm=off quiet splash
Lets hope that does the trick!
I did the same at first. But then my computer won’t shut down. I had to turn off with a switch.
I have reapplied this since receiving a kernel upgrade, and it is shutting down fine, and so far not getting that pesky beep!!
