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. Jerry

If you have a network, netconsole may be an option. If you are using UEFI boot, using pstore to save the panic message might work as well.
I also suppose that I could use SSH to login remotely and likewise grab logs.
If your kernel is in fact locking up, SSH will probably not be an option.

I managed to get a picture of the console. I posted everything here: https://bugzilla.kernel.org/show_bug.cgi?id=205017
