Hi again,

I actually forgot to quote the previous message describing the issue:

> KernelCI has identified a mainline boot regression [1] on the following
> AMD Stoney Ridge Chromebooks (grunt family), between v6.8 (e8f897) and
> v6.8-1185-g855684c7d938 (855684):
> - Acer Chromebook Spin 311 R721T (codename kasumi360)
> - HP Chromebook 14 (codename careena)
> - HP Chromebook 11A G6 EE (codename barla)
> 
> The kernel doesn't boot at all and nothing is reported on the serial
> console after "Starting kernel ...". The issue is still present on the
> latest mainline revision.
> The defconfig used by KernelCI for the boot tests can be found in [2].

sorry about that!
