           Summary: Amdgpu, Tonga "IO_PAGE_FAULT" and "[amdgpu]] *ERROR*
                    amdgpu: ring 0 test failed" result in Kernel Panic

            Status: NEW
          Severity: critical
          Priority: medium

Logfile

Switched from catalyst to amdgpu, Kernel 4.2 and Kernel 4.3 with powerplay
fixes crash, wenn modesetting is enabled (which just has to be, to get
everything working..) 
When booting without modesetting no Kernel Panic occurs, but just nothing else
works really good...

I'm using Archlinux with mesa/llvm etc build from git.
Kernel 4.2 is Archlinux vanilla kernel, 4.3 is build from
http://cgit.freedesktop.org/~agd5f/linux/?h=amdgpu-powerplay

Log files are attached.I've tried with disabled/enabled Iommu, it think this
Log is with disabled Iommu.

--- Comment #1 from Michel Dänzer <michel@daenzer.net> ---
I also get the I/O page faults with my Tonga, but AFAICT only when it's the
primary GPU, not when it's the secondary one. Also, the ring test doesn't fail
and acceleration works fine for me in either case, so I think the I/O page
faults and the ring test failure are two separate issues and should be tracked
separately.

These I/O page faults errors are quite annoying and delay boot for about 5
seconds. Should I open a separate bug report?

IMHO these should be reported.
I had such boot-up delays due to iommu page_fault flood
on HD 3870 and they are quite annoying.
