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.
