System freezes on dpms standby without kernel parameters #119

Closed koeppl closed 10 months ago

I switched yesterday to coreboot v8.50, and experience from now on that the system freezes when the system screensaver starts, which gets triggered via xset s . Pressing buttons sometimes results in a white flashing of the screen with gray vertical bars. At this state, the system is no longer responding such that only a forced shutdown by a long power button press works. The behavior can also be triggered deterministically via xset dpms force standby.

The kernel parameters i915.enable_dc=0 intel_idle.max_cstate=2 suggested in https://github.com/StarLabsLtd/firmware/issues/116 helped me to resolve the problem.

I thus wonder whether these parameters are necessary by default, or whether a bug has been introduced in the new coreboot version.

I experienced the problem with Debian 11 and Debian 12. The notebook is a StarLite Mk IV.

Could be - possibly even the same as #111. Will get 8.70 to the testing remote - should be available inside of 24 hours - can you try that?

Fixed in 8,94 which is now stable.
