Kernel 5.17 cause cause display problem after suspend

After upgrading to 5.17, my Thinkpad T495 laptop have problem resuming from suspend.
After calling:

 systemctl suspend 

and turning it back on, the fan spin, the power light is on, but there's no display.
Hibernate works as normal, only suspend is affected.
This is not a problem of the Graphical environment since the display don't even have light, and same can be reproduce in tty.
After downgrading to 5.16 or using lts kernel solve this issue.

Anyone have similar issue? Is there a way to solve this other than waiting for the next kernel version?
