Hi,
It seems unplugging the power cable on my HP Mini 9 netbook makes OpenBSD
5.5 panic. I just reproduced by booting up the machine and pulling the cord
without even logging into the system, the first time I tripped in the cable
by accident. See trace and ps below. plus56.html shows this line
"If acpi(4) finds a bogus interrupt, don't panic but print a message, to
workaround dodgy BIOS."
I could not find an associated bug number or changeset number to compare.
config_activate_children: device eephy0 failed 1
config_activate_children: device msk0 failed 1
panic: config_detach: forced detach of mskc0 failed (45)
Stopped at Debugger+0x4: popl %ebp
RUN AT LEAST ‘trace’ AND ‘ps’ AND INCLUDE OUTPUT WHEN REPORTING THIS PANIC!
IF RUNNING SMP, USE ‘mac ddbcpu <#>’ AND ‘trace’ ON OTHER PROCESSORS, TOO.
DO NOT EVEN BOTHER REPORTING THIS WITHOUT INCLUDING THAT INFORMATION!
