Description Alexei Gradinari 2023-09-01 20:28:03 UTC

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:

    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.
