Re: [PATCH 0/3] nouveau: fix 3 null-ptr derefs

[Lyude Paul <lyude@redhat.com>]

Hi, could you please specify what hardware this is, and why exactly you're
booting it without ACR firmware?

I'm not totally against these patches, but these cards really aren't meant to
be run with the ACR firmware these days. You're going to hit pretty regular
issues and bitrot pretty regularly if we don't just figure out why exactly
it's not loading - could you send a dmesg from when your system boots up so we
could take a look?
