Commit 7bc5a2b -- ACPI: Support _OSI("Darwin") correctly -- has introduced an intermittent boot failure on an IvyBridge Macbook Pro 13 (MacBookPro10,2). The failure rate is around 12%. This was diagnosed by doing a bisect with many boots for each kernel, then verifying failure on 7bc5a2b, and then booting 50 times again with the prior commit (9faf613) to verify that commit was ok (50 boots is necessary to get a high probability >99% of hitting this).

The Apple BIOS is MBP102.88Z.0106.B07.1501071215 01/07/2015 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
