Mint 12 Hangs. x64 AMD Athlon X2 (Dual Core)

Help!

I changed my AMD Athlon single core processor to Dual Core yesterday and re-installed Linux from scratch. My Windows partition I left as it was. Windows recognized the new dual core processor and re-validated the OS and has worked fine. Task manager shows two processors etc. Hooray!

But the Linux Mint 12 x64 install keeps freezing. Prior to upgrading the CPU the Linux Mint 12 x32 that was on there worked fine without any problems. I haven't changed anything else on the PC just the CPU (and then a re-install of Mint 12 x64). I decided to re-install Mint to the 64bit version as it's so quick and easy to do.

Anyone give me clues how I could narrow down where to look for the cause of the Mint system freezes? I get the impression that Linux and AMD Athlon X2 processors did have problems in the past. Not sure if this is still the case.

Thanks!

Did you only run 32-bit Linux on the old CPU? And, have you ever booted the existing Mint 32-bit between the CPU replacement and the reinstall?

Yes after the CPU replacement the 32bit did hang once. I have also run off a live 32 bit CD and this also hangs. Prior to the CPU replacement the Mint was fine - absolutely no problems.

Isolated it down to the wireless card (TP-Link TL-WN851ND). When I enable a wireless connection Linux freezes. If I disable wireless and just use wired connection it works fine.

This wireless card worked fine with Linux Mint 9 (with the old single core Athlon processor).

Maybe the same?

The Linux 3.3 kernel should include the fix for that bug.

Oh yes, thanks for telling me that it's not a good idea to buy a TL-WN851ND.
