<pre>Since 4.7 kernel, qxl drm driver spews the errors when using VT:
kernel: [TTM] Buffer eviction failed
kernel: qxl 0000:00:02.0: object_init failed for (4026540032, 0x00000001)
kernel: [drm:qxl_alloc_bo_reserved [qxl]] *ERROR* failed to allocate VRAM BO
In my test case, just install a QEMU/KVM VM with QXL interface, login GUI, and
then switch to VT1. At login there, the error appears repeatedly.
4.6 kernel works fine.
The git bisection spotted that it was introduced by
6819c3c2517604f979da3de773f2420e07dd4f4b
drm/qxl: Use drm_fb_helper deferred_io support
