I also ended up with a blank screen followed by a reboot, which showed some |
| 30 |
partitions were not unmounted cleanly, followed by repeated reboots in the |
| 31 |
same fashion, until I interfered to stop this madness. I then booted with the |
| 32 |
previous kernel and as my first task I disabled some framebuffer setting, which |
| 33 |
I now fail to recall! LOL! |

I think it is this one: |

======================= |
| 37 |
CONFIG_DRM_SIMPLEDRM: |
| 38 |
|
| 39 |
DRM driver for simple platform-provided framebuffers. |
| 40 |
|
| 41 |
This driver assumes that the display hardware has been initialized |
| 42 |
by the firmware or bootloader before the kernel boots. Scanout |
| 43 |
buffer, size, and display format must be provided via device tree, |
| 44 |
UEFI, VESA, etc. |
| 45 |
|
| 46 |
On x86 BIOS or UEFI systems, you should also select SYSFB_SIMPLEFB |
| 47 |
to use UEFI and VESA framebuffers. |
