Fwd: Kernel version 6.1.50 regression: radeonfb deactivate vga console

[Bagas Sanjaya]

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.

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.
