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:
[ 2.382984] console [hvc0] enabled
[ 2.382984] console [hvc0] enabled
[ 2.382984] console [hvc0] enabled
[ 2.382984] console [hvc0] enabled
[ 2.382984] console [hvc0] enabled
[ 2.382984] console [hvc0] enabled
..
(see attached file titled bad.log)
If I use Linus's latest git tree and revert your patch I get the kernel
to bootup (see good.log file),
