the first thing I tried to do was boot with kernel 5.11 (or to be more precise,
with several previous kernels).
it didn���������t work.
after that I tried to update the kernel and firmware from the KERNEL:HEAD
repository, but that didn't help either.
unfortunately I didn't have more time for the investigation, tonight I will try
to install the kernel from home:/tiwai:/kernel:/drm-tip/standard/
