I'm having real stability problems with recent kernels. The system
runs fine for a few minutes,
sometimes for a couple of hours, then stops with the attached oops. Any
ideas what is going on?
Also with recent kernels the APIC detection seems to be dodgy...
The top of my log says:
Jun 16 22:48:56 spock kernel: OEM ID: _AMI_ Product ID: 840_CARMEL__
APIC at: 0xFEE00000
Jun 16 22:48:56 spock kernel: Processor #0 Pentium(tm) Pro APIC version

Jun 16 22:48:56 spock kernel: Internal APIC present.
Jun 16 22:48:56 spock kernel: Bootup CPU
But further down I get...

Since it has clearly identified the APIC earlier, it appears to have
forgotten about it later.
