>Description:
Booting current with an AMD Radeon R7 240 videocard in a machine with
an Intel Haswell chipset gives me 2 errors:

[     3.686110] radeon0: autoconfiguration error: error: failed VCE resume (-60).

and

[     3.686110] [drm] radeon: irq initialized.
[     3.966110] {drm:netbsd:r600_ring_test+0x244} *ERROR* radeon: ring 0 test failed (scratch(0x850C)=0xCAFEDEAD)
[     3.966110] radeon0: autoconfiguration error: error: disabling GPU acceleration

No idea yet about the last error, fix for the first one was fairly easy to find.

>How-To-Repeat:

Boot my machine.
