I have met a bug with the same error message, its cause was that the bios
did not allocate RMRR/DRHD(can't remember which one) for the device.
Thanks

Now I have 3 extra messages talking about handling a fault status. lspci says
00:1f.2 is:
00:1f.2 SATA controller: Intel Corporation 7 Series Chipset Family 6-port SATA
Controller [AHCI mode] (rev 04)
This could be caused by some change in the SATA driver stack. Maybe a
DMA buffer is used after unmap or something.
If this doesn't ring any bells, I'l go do the bisect thing...
Yes, a bisection would help here, thanks for doing this.
