Hi, commit 84b79f8d2882b0a84330c04839ed4d3cefd2ff77 (drm/i915: Fix crash while aborting hibernation) introduced two new issues which were not present in 2.6.33-rc7: - every second resume from hibernate results in a blank screen - the annoying flash at the end of atomic copy/restore during the hibernate proces... 17 Feb 2010 14:30

[PATCH] spi_s3c24xx: Fix for SPI on S3C2412
Hi, Testing some SPI temperature sensors and ADCs with a S3C4212 host I have found that I could not read the correct data. I've probed the SPI signals with a scope and everything seemed OK. I dig into the driver sources and on the S3C2412 datasheet to find that this device can not use the same S3C2410 driver... 17 Feb 2010 13:22

[patch 0/2] pci: raw_spinlock annotations
Preempt-RT converts spinlocks to sleeping spinlocks, but some spinlocks need to be kept as real spinlocks. In 2.6.33 we merged the spinlock namespace cleanup which allows us to annotate those locks. The lock type is changed to raw_spinlock which is the same as a common spinlock in !RT kernels. The following seri... 17 Feb 2010 09:57
