So v4.19 is still failing for me ...

Test results for stable-v4.19:
    11 builds:  11 pass, 0 fail
    22 boots:   22 pass, 0 fail
    32 tests:   30 pass, 2 fail

Linux version:  4.19.99-rc3-g041f280e6a1a
Boards tested:  tegra124-jetson-tk1, tegra186-p2771-0000,
                tegra194-p2972-0000, tegra20-ventana,
                tegra210-p2371-2180, tegra30-cardhu-a04

However, I am not seeing any issues with v4.14, so still not clear what
is going on here.

Cheers
Jon
