Blank screen on boot of Linux 6.5 and later on Lenovo ThinkPad L570

[Jaak Ristioja]

Hello,

Upgrading to Linux 6.5 on a Lenovo ThinkPad L570 (Integrated Intel HD 
Graphics 620 (rev 02), Intel(R) Core(TM) i7-7500U) results in a blank 
screen after boot until the display manager starts... if it does start 
at all. Using the nomodeset kernel parameter seems to be a workaround.

I've bisected this to commit 60aebc9559492cea6a9625f514a8041717e3a2e4 
("drivers/firmware: Move sysfb_init() from device_initcall to 
subsys_initcall_sync").

Any ideas?

Best regards,
Jaak Ristioja
