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,

Here is a sample output during bootup:
