the kernel works


but I don't really understand why you set "linux (Ubuntu Focal)" to invalid

as said the patch should be back ported to all 5.11 kernels 

i use the HWE kernel in Focal and it was recently pushed to 5.11 

but according to the ticket description you added the linux-oem-5.13 kernel - i honestly don't understand that - but anyway
