Dear Sir,

Tried out 

intel_pstate=hwp_only 
and
intel_pstate=no_hwp 

and none of these worked.  Still same situation.  Bios has been updated and I 
have to use nomodeset as kernel parameter to successfully boot.  Maybe another 
kernel 6.7.5 coming soon will fix the situation?

was not able to capture kernel output of journalctl :(

Best Regards,


Antonio
