Hi there,
I'm not sure this is the proper place to send this, so please tell me
if I should send this mail to another mailing list or file a PR about
this.
I used freebsd-update to upgrade from 7.2-RELEASE-p3 to 8.0-RC1.
Everything went fine, but I had to regenerate my wireless card
(Realtek RTL8180L) module with ndisgen. However, when I load the
generated module with kldload I get a kernel panic and the system
reboots. I also have a 67mb vmcore; I can try to make it available if
needed.
I'll paste some sections from core.txt; I can attach the whole file if you want.
