You mean the messages themselves are translated? That's weird. Seems
that Google Translate somehow kicks in. There is a "Offer to translate
pages that aren't in a language you read" setting in chromium, but I
guess if you have only English in languages it should not matter... I
am out of ideas. Just in case, all syzbot reports are on LKML as well.
