> I've got random crash on 4.1.1-Stable.
>
> I just updated the system 30 min. ago, and it just crashes
> when I make ports (or kernel, system).
> It says fatal error 12 (page fault in kernel mode).
> The debug message is:
You need to:
a) Provide a dmesg listing from a boot -v of your system
before the problems began.
b) Perform an nm /kernel | sort and locate the function that
contains the instruction 0xc01f7758.
or even better yet
c) put options DDB into your kernel config file and provide
the output of "trace" when you system panics.
