One of them was merged which seems to have made my machine stable at least and fixes a problem related to the MMC. The second one we may need is a power related changed to SPI to hold the CPU in C0/C1 whenever the ACPI _SEM is held. Graphics shows these problems up because of the way the GPU causes power state changes. Alan
