Setting up to debug kernel

[Jerry DeLisle]

I have a fairly new processor and motherboard. I recently upgraded the BIOS on 
this system and found that the kernel just locks up, everything freezes within a 
few minutes.  I want to see if I can capture any data from the kernel as this 
happens.

My first thought is to try to connect via a serial port or similarly a USB based 
port and get some sort of continuous stream of log data that I can capture on 
another machine.

I also suppose that I could use SSH to login remotely and likewise grab logs.

Regardless I am looking for recommended best approach here.  I suspect a driver 
issue, so I am going to try to boot to runlevel 3 with just basic console (fancy 
graphics interface) and proceed from there.

Any pointers would be appreciated.
