Hello @bugs,
I have an SGI O2 (IP32 processor) that has been running 5.8 release just
fine. I finally got around upgrading it to 5.9 -current and hit this
kernel panic. On the initial reboot after (U)pgrading and installing the
base system. I did a reboot a few minutes later and hit it at exactly the
same spot.
Given that there typically aren't a ton of people on this processor
architecture, I thought it would be best for me to share the full report as
quickly as I found it.
I'm including the serial console output, the traceback, the process list,
and for good measure the output of 'show uvm' and 'show bcstats' on the off
chance this is filesystem related.
I've upgraded with this same snapshot kernel on my amd64 machine, my hppa
machine and my alpha machine and they are all happy as can be. I'll try my
sparc64, macppc and i386 machines when can get a chance.
Any ideas? Happy to work with someone and gather any information needed.
My apologies in advance if I misread any of the documentation on what
information is needed to report a kernel panic.
Data follows:
Cannot connect to keyboard -- check the cable.
Cannot open keyboard() for input
