Bug Description
When booting 2.6.32-24 my onboard network card does not detect a link and is not initialized. Both lights are fixed on. During the boot the CPU jump on 1 core to between 30-100% pulsating in about 2 second rhythm and generating continupously a load of about 2.
System performance is severely degraded with frequent relatively brief freezes and very sluggish response.
Booting in 2.6.32-23 works perfectly normal.

I tried with the latest mainline kernel and this works fine.

Linux pti-laptop 2.6.32-
AFAICT the symptoms only happen when using 2.6.32-24
