I've upgraded from F15 to F16 and noticed that I have a problems with hardware detection. Upon loading I can see message like

CPU#1 not responding

on the screen. It disappears and I can login then as usually. But I have only 1 CPU in System Monitor and it is always loaded by 80-100%. So my PC is very noisy. :) I've noticed also that Caps Lock indicator is always on irregardless of actual caps lock status. And the system freezes out after 5-10 minutes. :(

I've tried clean install of F16 and the problem is the same.

My PC is Compaq Presario CQ56-118EO with Intel Pentium Dual Core T4500 CPU. I've tried to google but failed.

Is my hardware/BIOS/karma incompatible with Linux 3.x?

dmesg output

P.S. I upgraded my BIOS to the last version available at HP site dated back to April of 2011. No changes...

P.P.S. Not Foedora specific. Exactly the same situation with openSUSE 12.1

    3.x didn't actually change anything, Linus just decided it was time to call it 3.0.

Well... Seems like i found out a solution. At least it worked in my case so it's a worth try.

  1. Turn off PC.
  2. Disconnect the power cord.
  3. Remove the battery.
  4. Wait a bit.
  5. Insert the battery.
  6. Connect the power cord.
  7. Turn on PC.
  • 1. I forced to do this trick EVERY start. 2. After 5 minutes it freezes anyway.
