I'm currently bisecting on two machines (sata_mv and sata_nv). sata_mv suddenly started spewing errors in recent kernels, but kernels from ~48 hours ago are just fine. AMD64 sata_nv machine will simply lock up if I push it too hard. Again, reproducible, and kernels from ~48 hours ago are fine. AHCI machine so far seems fine (kernel ~24 hours ago), storage-wise, but the hda_intel audio decided to stop working :) I'm quite happy to test patches, but I never run with DEBUG_PAGEALLOC so that shouldn't be causing the problems here.
