If -P is not supposed to activate the serial console, then the boot.config(5) manpage is in urgent need of a fix.

I already have tried all kinds of different combinations when I sat in front of the box yesterday. I'm not sure if I have tried the exact combination that you suggest, though. I also don't understand why those changes should improve anything. Anyway, I will try next time I'm near the machine (it's a three hours ride) which will probably be on Friday. If it won't work then I'll downgrade it to 7.1 the same day. BTW, the interesting thing is that all processes that try to access the console hang in "ttydcd". I'm not familiar with the tty code ... Does anyone have an idea what this means? Best regards Oliver -- Oliver Fromme, secnetix GmbH & Co. KG, Marktplatz 29, 85567 Grafing b. M.
