| OpenBSD/vax 5.8 Kernel Panic and Crash |
Trouble started when I tried to build packages from the OpenBSD ports collection. My first build attempt for shells/bash caused a kernel panic and crash, a very rare occurrence in all of my forays into classic BSD and Unix varieties for different architectures.
I tried various things, like falling back to the "classic" SIMH version 3.9 and disabling the swap space on the second disk. The kernel panic is persistent, and I will have to come back to this and spend more time researching it. Part-2 of this saga will be posted some day.
The kernel panic and crash is consistent:
panic: rmpage: pg 0x80635ad8 br 0x88044300
Stopped at rmpage+0xc7: cmpl 8(r6), r2
RUN AT LEAST 'trace' AND 'ps' AND INCLUDE OUTPUT WHEN REPORTING THIS PANIC!
DO NOT EVEN BOTHER REPORTING THIS WITHOUT INCLUDING THAT INFORMATION!
