   When I boot Linux 5.15.0-83 (ubuntu) I get the following errors:

kernel: [    0.309332] ACPI BIOS Error (bug): Could not resolve symbol [\_SB.PCI0.LPC0.EC0], AE_NOT_FOUND (20210730/dswload2-162)

kernel: [    0.310927] ACPI: 17 ACPI AML tables successfully acquired and loaded
kernel: [    0.312125] ACPI: [Firmware Bug]: BIOS _OSI(Linux) query ignored

The System is running fine but I have a strange behavior on reboot.

If I reboot the system it only boots into the grub command prompt until I either boot from an USB disk or into Windows 11 on the same machine, and if I then reboot I get the grub boot menu again (?).

I made an EFI Firmware update to v1.29.AS01, tried a Linux 6.2 kernel, got the same errors and the system won't boot at all (but with Linux 5.15 it still does).
