Hi, Thanks for the advice. I installed kernel version 6.1.8. The problem is still there. The update did however solve some other issues related to Nvidia drivers and it seems the GPU now works with CUDA at least. Adding "nomodeset" to kernel boot parameters had a surprising effect: the system freezed while booting with a UBSAN error. I see this on my screen just before the hang: ACPI BIOS Error (bug): Could not resolve symbol [\_TZ.ETMD], AE_NOT_FOUND (20220331/psargs-330) ACPI Error: Aborting method \_SB.IETM._OSC due to previous error (AE_NOT_FOUND) (20220331/psparse-529) Bluetooth: hci0: Malformed MSFT vendor event: 0x02 ================================================================================ UBSAN: array-index-out-of-bounds in /build/linux-6.1.8-rcVqSn/linux-6.1.8-6.1.8/drivers/acpi/acpica/dswexec.c:401:12 index -1 is out of range for type 'acpi_operand_object *[9]' ================================================================================ BR, Topi On ti, 2023-01-31 at 06:09 +0000, Zhang, Rui wrote: > This seems like a graphics issue. > Please confirm if the problem still exists with LATEST vanilla kernel. > If yes, please boot with kernel parameter "nomodeset" and see if the > problem is still there. > > thanks, > rui > > On Mon, 2023-01-30 at 06:52 +0000, Topi Mäenpää wrote: > > Hi, > > > > I hope I'm not breaking rules by posting this question here.
