The other suspend failure on my platform is iprb driver for pci8086, 1209 apart from vgatext for(0x8086, 0x8108).
Any update on the iprb fix for cpr support coming soon. could you please let me know the source location of iprb driver. first I would like to focus on DDI_SUSPEND and DDI_RESUME portions of iprb driver than the i915/vgatext support. I tried: uadmin 3 101 uadmin 3 102 uadmin 3 24 (to skip suspend failures). Some times suspend hung trying iprb, but completes full suspend resume, with resumes has more failures than suspends.
