I upgraded the kernel to 4.17.8 and experienced the issue again. Not
sure if the bug is the same technically, but the sympthomes are: I tried
to upload a 30 MB file, and in the midst got a noisy screen. I will try
to catch it with kdump to get the backtrace again later.

This issue should be fixed by commit

which has been backported to v4.17.3, v4.16.18 and v4.14.52. Please
check again with one of those kernel versions (or newer).
I see now that the fix doesn't apply cleanly to v4.9 stable due to
unrelated context changes. I'll go fix that and resubmit a backport for
v4.9, so we get the fix into "stretch" too. Thanks for reminding me.
