When booting, I now see the following

Failed to request firmware: -2 Mar 04 15:44:37 thehive kernel: intel_vpu 0000:00:0b.0: probe with driver intel_vpu failed with error -2

The intel_vpu error was present in T105, but the ACPI Errors were not. I would like to downgrade to T105, but the folder is empty on the download page.

Kernel release = 6.13.5-arch1-1

Thank you for your help.
