142788: j4105 with 4.20 - drm tip full dmesg from boot via journalctl
The problem reproduces on every boot. It always hangs while iommu is enabled;
Sometimes - with other kernel or after soft reboot - the error messages are a
bit different, but I'm not sure - I lost them after reboot.
Nothing changed after updating from 4.19 to more recent kernel - ubuntu's build
of drm-tip. The exact verison of new kernel is:
Linux version 4.20.0-994-lowlatency (kernel@gloin) (gcc version 8.2.0 (Ubuntu
8.2.0-12ubuntu1)) #201812142101 SMP PREEMPT Sat Dec 15 02:06:59 UTC 2018
