This "dead at boot time" issue is impacting the general ability to test
patches against latest -git in time for the current merge window.

In the meantime, does the patch I sent out help people? I'd like to get feedback, but I'm a lazy bum, and don't use DEBUG_PAGEALLOC myself, so I was hoping that people who actually see this could comment on my untested suggestion.

Oh.. so this bug is supposed to only bite with DEBUG_PAGEALLOC=y ??

Then something else is broken, perhaps.  I just saw a long traceback
scroll off the top of the screen, with lots of bio_* functions in the list
and assumed it was the same bug.

Mmm.. I'll get out the camera and try it again now..

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.
