Having Raptor Lake-P laptop (Dell Precision 3581, 13th Gen Intel Core i7-13700H), i915 driver with SR-IOV brings the issue with sleep mode. Even without /sys/devices/pci0000:00/0000:00:02.0/sriov_numvfs initialization the system (Fedora 38) unable to get back from sleep - only power-off via button longpress can reset it.
I tried i915 as DKMS module with various kernel versions up to 6.3.8 and just plain Intel LTS kernel from this repo (including today's 6.1/linux branch) - the behavior is the same: everything works, I even have Windows QEMU VM with vGPU passed through with great FPS in 3D tests, but... the host just hungs forever right after sleep. I tried to disable rc6, most of "workarounds" in boot string, nothing helps. I would appreciate any idea that will help to remove this roadblock on the way to have a great SR-IOV Iris XE feature.
