Date: Tue, 23 Sep 2014 22:11:15 +0200 Message-ID: <5421D3E3.6080805@gmx.de> Mime-Version: 1.0 Content-Type: text/plain; charset=ISO-8859-1; format=flowed To: linux-kernel@vger.kernel.org, linux-serial@vger.kernel.org, linux-parisc Return-path: List-ID: List-Id: linux-parisc.vger.kernel.org During the release cycle of v3.17 I've seen sometimes a broken serial console output on the parisc platform. Interestingly all kernel messages printed by the kernel via printk() show up correctly, but output from userspace (e.g. by the init process during boot) show up as random bytes. Since the printk() output is correct the serial port itself and setup is probably correct. Is parisc the only arch which has this problem, or are other architectures affected as well? Maybe someone has an idea what could be wrong? I did not try to bisect it yet. Thanks, Helge Here is a sample output during bootup: ... usb 1-2: Manufacturer: SILITEK rs og ]f" s l random: nonblocking pool is initialized net eth0: Setting full-duplex based on MII#1 link partner capability of 45e1 tpdsystemd-udevd[744]: starting version 215 . eg.. vp.. ..Adding 1350652k swap on /dev/sdb6.
