Ubuntu Lucid 10.04, Freezes/Lock-ups Solution

According to my previous post on Ubuntu Freezes, you can IGNORE that!
It will solve the "freezes" problem but, it will disable Hyper-Threading (Multiprocessor) capabilities.

Here's the best solution ~ DISABLE the "Advance Programmable Interrupt Controller" (APIC)

Steps.

1. Go to terminal ~ Application > Accessories > Terminal
2. Type in: "sudo gedit"
3. Enter password if required
4. Open grub file ~ File > Open and find grub file
5. Open grub file which located in etc/default directory
6. Add "noapic" at "GRUB_CMDLINE_LINUX_DEFAULT=" eg: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash noapic"
7. Once done, safe the file
8. Then, at terminal, type in: "update-grub" to update the file.
9. Restart!

The grub file might looks like this:

# If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.
GRUB_DEFAULT=0
#GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=10
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash noapic"
GRUB_CMDLINE_LINUX="" 

# Uncomment to disable graphical terminal (grub-pc only)
#GRUB_TERMINAL=console 

# The resolution used on graphical terminal
# note that you can use only modes which your graphic card supports via VBE
# you can see them in real GRUB with the command `vbeinfo'
#GRUB_GFXMODE=640x480 

# Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux
#GRUB_DISABLE_LINUX_UUID=true 

# Uncomment to disable generation of recovery mode menu entries
#GRUB_DISABLE_LINUX_RECOVERY="true" 

# Uncomment to get a beep at grub start
#GRUB_INIT_TUNE="480 440 1"

Cheers!
