Yeah, use git only :-)
Anyway, still b0rked although I can get further and actually suspend.
Full splat below.
The IOMMU PFs point to
01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] RV635 [Radeon HD 3650/3750/4570/4580]
and
00:12.0 USB controller: Advanced Micro Devices, Inc. [AMD/ATI] SB7x0/SB8x0/SB9x0 USB OHCI0 Controller
respectively.
and the IOPFs are all this OHCI controller. Which points at a timing
problem during suspend, I'm being told, when the device gets returned
to the BIOS but IOMMU is still on and filters accesses. Or something to
that effect. In any case, still b0rked.
-> start suspend to disk:
