Subject: Fwd: Kernel version 6.1.50 regression: radeonfb deactivate vga
 console

Hi,

I notice a regression report on Bugzilla [1]. Quoting from it:

> Since kernel version 6.1.50 the VGA console stopped working on all HP ProLiant (G6 and G7) servers with [AMD/ATI] ES1000 VGA controller.
> 
> No issue with all kernel version 6.1.X before 6.1.50.
> No issue with the kernel 6.1.50 with the reversed next commit:
> 
> commit 6db53af15444e7022640d7b8d5e7531d94e27a43
> Author: Daniel Vetter <daniel.vetter@...ll.ch>
> Date:   Wed Jan 11 16:41:08 2023 +0100
>     fbdev/radeon: use pci aperture helpers
> 
> With the commit 6db53af15444e7022640d7b8d5e7531d94e27a43 there is kernel log "radeonfb 0000:01:03.0: vgaarb: deactivate vga console" and VGA console not working. Without this commit no such log and VGA console working.

See Bugzilla for the full thread.

Anyway, I'm adding it to regzbot:

#regzbot introduced: 9b539c4d1b921b https://bugzilla.kernel.org/show_bug.cgi?id=217861
#regzbot title: using pci aperture helpers deactivates AMD ES1000 VGA controller

Thanks.
