Re: [gentoo-user] Anyone's kernel getting panicky????

[Alex Thorne]

I'm on 4.1.2 with no problems. Sorry to check the obvious, are you sure you
copied your config over from your previous kernel? The only time I got a
kernel panic after a minor kernel upgrade was when I forgot to do this and
as a result compiled the default kernel without support for LVM.
