Thx for the report. FWIW, regzbot noticed there is a patch that refers
to the culprit that might have been landed in next after your test ran
for the last time (and meanwhile it was mainlined): f100ce3bbd6 ("media:
verisilicon: Fix crash when probing encoder")

I wonder if that is related or might even fix the issue.

Ciao, Thorsten
