After playing around with a lot of dual-boot configurations, I've recently decided to ditch Windows (8.1) altogether and have installed Linux Mint.

I am running Mint 16 Petra with MATE Desktop

This issue hasn't caused any harm that I know of, and hasn't really interfered with anything.

When I lock my laptop, or just close the lid, I open it up to find a few lines being spat out at me saying I have a firmware bug. They are quickly replaced by the dialog box requesting for my password to unlock the computer, but I have managed to take a picture of the errors.

They are a series of errors that say:

[*some numbers*] [Firmware Bug]: cpu *X*, try to use APIC500 (LVT offset 0)
for vector *some hex*, but the register is already in use for vector *more hex*
on another cpu
  • It seems the some numbers are different each time
  • The X is either cpu 1, 2, or 3 (in sequence for each line)
  • The first set of hex is always 0x400
  • The second set of hex is always 0xf9

My Laptop:

  • TOSHIBA Satellite S855D Version PSKG2U-028005
  • AMD A10-4600M APU with Radeon HD Graphics
  • Kernel: 3.11.0-12-generic x86_64 (64 bit, gcc: 4.8.1)
  • Bios: Insyde Version: 6.30

Has anyone had experience with this? Need anymore info on the computer or distro?

  • This issue actually causes a system slow-down for me.

Seems it is a BIOS bug that is very common on AMD platforms.
