Comment 21 for bug 1742675

Yes, probably differences in results due to different hardware.

But based on your and my test results i see 2 probably different problems:

1. Mine looks quite well as a result of some Ubuntu patch applied in 4.13.0-26 and above - i can use without problems all mainline kernels and all kernels up to 4.13.0-25.

2. Your problem is really less predictable and random results.

But this is only my maybe false assumption.
