[Intel-gfx] i915 driver failure
Hi all, I hope I'm sending this to the correct mailing list (if not, please, suggest a proper one). I'm using kernel 3.17.4 32-bit (custom build) and during boot I got a crash in i915 driver. It happens on the motherboard with old BIOS, newer BIOS version works ok. Anyway, I assume driver shall not crash regardless of BIOS version. Here it is a copy of kernel log: Nov 28 13:47:05 kernel: [0.264801] Non-volatile memory driver v1.3 Nov 28 13:47:05 kernel: [0.264988] [drm] Initialized drm 1.1.0 20060810 Nov 28 13:47:05 kernel: [0.265695] pci :00:00.0: Intel GMA3150 Chipset Nov 28 13:47:05 kernel: [0.265816] pci :00:00.0: detected gtt size: 524288K total, 262144K mappable Nov 28 13:47:05 kernel: [0.265958] pci :00:00.0: detected 8192K stolen memory Nov 28 13:47:05 kernel: [0.266148] [drm] Memory usable by graphics device = 512M Nov 28 13:47:05 kernel: [0.266239] [drm] Replacing VGA console driver Nov 28 13:47:05 kernel: [0.266983] Console: switching to colour dummy device 80x25 Nov 28 13:47:05 kernel: [0.273080] i915 :00:02.0: irq 27 for MSI/MSI-X Nov 28 13:47:05 kernel: [0.273101] [drm] Supports vblank timestamp caching Rev 2 (21.10.2013).

I've tested this patch on the failed system (BIOS ver.1.0) with 3.17.4 kernel and it looks good. - Do you need dmesg log? - Could this patch be merged into 3.18 kernel? I've also checked that everything still ok on other mobos with BIOS ver.1.0c and 1.2a. One more question slightly out off topic: - could I use i915 driver with other Intel Atom CPUs, such as D2550 and Avoton C2550?
