>Description:
When loading if_xl and miibus.ko from boot loader (via loader.conf),
typing ifconfig results in a kernel panic. Panic reason being "page fault -
error in supervisor read" .. I wish I had a dump, however apparently /var
was not to capacity..
>How-To-Repeat:
Load if_xl and miibus from boot loader and type ifconfig after booting.
Or let rc.network go through if you have any ifconfig_xl0* lines in rc.conf.
>Fix:
I wish I knew ;)
