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)
- Go to terminal ~ Application > Accessories > Terminal
- Type in: "sudo gedit"
- Enter password if required
- Open grub file ~ File > Open and find grub file
- Open grub file which located in etc/default directory
- Add "noapic" at "GRUB_CMDLINE_LINUX_DEFAULT=" eg: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash noapic"
- Once done, safe the file
- Then, at terminal, type in: "update-grub" to update the file.
# If you change this file, run 'update-grub' afterwards to update
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash noapic"
# Uncomment to disable graphical terminal (grub-pc only)
# 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'
# Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux
# Uncomment to disable generation of recovery mode menu entries
# Uncomment to get a beep at grub startCheers!
