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@xxxxxxxx> > 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. > > Equipment: > HP ProLiant DL360 G7 > 01:03.0 VGA compatible controller: Advanced Micro Devices, Inc.

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.
