I've upgraded from 2.6.32 and I get a blank screen when the system is starting KMS. My motherboard is an Intel DG43NB with onboard video. I traced back to the patch that stopped working on my system and it is patch-2.6.32-git7. patch-2.6.32-git6 works fine. From dmesg of git7 I see this: i915 0000:00:02.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16 i915 0000:00:02.0: setting latency timer to 64 mtrr: type mismatch for c0000000,10000000 old: write-back new: write- combining [drm] MTRR allocation failed.
