[ 0.004012] ACPI: Reserving PCCT table memory at [mem 0xd8b68fb0-0xd8b6901d] this the output from a box that everything is working OK: [ 0.000000] ACPI: Reserving PCCT table memory at [mem 0xd8b68fb0-0xd8b6901d] I even compare the difference between grub before and after upgrade, and new sys-boot/grub-2.06-r6 inserted line: # Comment if you don't want GRUB to pass "root=PARTUUID=xxx" parameter to kernel GRUB_DISABLE_LINUX_PARTUUID=false but the above two lines are on my other boxes as well afater upgrade and text messages from kernel boot showing OK On 4/23/23 18:07, David Souza wrote:
Is your framebuffer device showing in /dev? It should be called /dev/fb0,1,2..... If yes could you post the output of $ dmesg | grep fb0 On Sun, Apr 23, 2023, 22:31 <[email protected] <mailto:[email protected]>> wrote: No, I did not change anything, during kernel upgrade only run: make oldconfig but nvidia-drivers-525.105.17 compiled with a note: WARN: setup Detected potential configuration issues with used kernel: CONFIG_FB_SIMPLE: is set, recommended to disable and switch to FB_EFI or FB_VESA as it currently may be broken with >=kernel-5.18.13 + NVIDIA: https://github.com/NVIDIA/open-gpu-kernel-modules/issues/341 <https://github.com/NVIDIA/open-gpu-kernel-modules/issues/341> (feel free to ignore this if it works for you) Though, I got same note compiling nvidia-drivers-470.182.03 and kernel boot normally showing text.
