Hey Miche.

The git commit 361162459f62dc0826b82c9690a741a940f457f0:

    hvc_console: display printk messages on console.

is causing an infinite loop when booting Linux under Xen, as so:

Ick, not good, thanks for letting us know.

Indeed. I am wondering why it was put in a tree and sent to Linus without
any Acks or even being replied to by anyone.  It appeared in the tty tree
between Oct 14 and Oct 25 (while I was unfortunately on vacation).  If
anyone had tried to boot this on any PowerPC server, it would have been
immediately obvious (as it was when I booted Linus' tree last night).

And the original author expressed doubts as to his understanding of how
it should all work anyway.

Just a little more care, please.

I would vote for reverting the original and having it resubmitted with
corrections at some later date.

You are right, I will go do that, sorry for the problems.

Ping ...

Linus can you please just revert 361162459f62dc0826b82c9690a741a940f457f0
"hvc_console: display printk messages on console" as it breaks consoles
for all PowerPC server machines.
