Bug ID: 245837
Summary: Switch from vga to fb on console fails after t359957
Product: Base System
Version: 12.1-STABLE
Hardware: amd64
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: kern
Assignee: b...@freebsd.org
Reporter: rkober...@gmail.com
After a recent update, my system locked up when attempting to switch from vga
to fb. The screen and does not ever proceed. Since the network is not yet up
and the system is still single user, I have been able to get more information.
I bisected to find that 359957 was the culprit.
If is possible that this is a drm issue that was hidden before this change, so
I will post a note about this to x11. I have seen reports on x11@ of problems
with systems locking up with blank screens, so this might tie into those.
My system is an old T520 with Sandy Bridge GPU.
Let me know what other information I might be able to obtain.
