            Bug ID: 110733
           Summary: [Regression] Kernel 4.19.x + linux-firmware 20190514 +
                    Vega 64: boot fails
           Product: DRI
           Version: unspecified
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/AMDgpu
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: mezin.alexander@gmail.com

Copying https://bugzilla.kernel.org/show_bug.cgi?id=203627 here, as I'm not
sure where to report the issue (and got no response in kernel bugzilla so far)

After linux-firmware upgrade from 4b6cf2bd1a9d53caa087403d943e7695009c1d0c to
711d3297bac870af42088a467459a0634c1970ca (20190514), 4.19 kernels (at least
4.19.40-4.19.45) don't boot anymore. Early during boot the monitor turns off,
and, apparently, the system hangs. Can't connect over SSH, SysRq keys don't
work. Also the failed boot attempt doesn't get recorded by journald.

Kernels 5.0 and 5.1 still boot completely fine. Also, 4.19 kernels boot if I
downgrade firmware back to 4b6cf2bd1a9d53caa087403d943e7695009c1d0c.

Apparently, these problems are caused by
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/commit/?id=2579167548be33afb1fe2a9a5c141561ee5a8bbe

GPU: RX Vega 64 (Sapphire Nitro+, vbios_version: 113-D0500110-O01)
Distro: Arch Linux
Archlinux bug: https://bugs.archlinux.org/task/62666

This is caused by vega10_sos.bin
Still happens with linux-firmware 20190618 and linux 4.19.56

Kernel starts booting with firmware 20190618 after commit
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=bfcea5204287b0a09dac71fa56a5d066d94d9bb1

Unfortunately, when I apply that patch to 4.19.59, compilation fails, so I
don't know if it's enough

With linux-firmware 20191022 + kernel 4.19.80 the system doesn't boot again

Is it possible to backport
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=bfcea5204287b0a09dac71fa56a5d066d94d9bb1
to 4.19?
