This would very likely be an Ubuntu kernel issue. As well as running a pre-release development version of these kernels on a pre-release version of (K)Ubuntu :smiley:

I think they are still shooting for a 7.0 (formerly known as 6.20) kernel before release in April.

Ok. Be waiting… but some strange. I go back to 6.19.0-5 and sometime get same problem too. Nothing changed in BIOS or somewere.
