Kernel panic booting 2022-Aug-21 15:18 nightly iso #319

Closed markshank closed 6 months ago

markshank commented 2 years ago

Booting ravynOS_0.4.0pre5_f14_5654957775912960_amd64.iso on VM (qemu/kvm) fails with a kernel panic.

If I reduce the virtual cpu count to one, then it boots without issue.

Serial console output below:

You get crashes consistently with CPU count > 1?

markshank commented 2 years ago

That was on the VM that has the VGT-g mediated passthrough iGPU that confuses the driver into acting like it has the full physical device. Many errors thrown by i915kms and drm. Not sure I would put much effort into it until we have i915kms up to speed.

I hope to test i915kms on bare metal this weekend. And barring any surprises, offer up my first PR.
