Hi All,
Any status of acceptance of this?
I changed the ioctl to an unlocked ioctl and removed the temperature ioctl call.
It's now in my linux-2.6-watchdog-next tree. Can someone verify that it still
works?
Seems that we are in interrupt, doing hvc_poll, which does
tty_flip_buffer_push
Which means that someone has tty-low_latency set and is calling
tty_flip_buffer_push in an IRQ. That has never been allowed or safe, and
now it hurts ;)

Hello Benjamin
Thank you very much for your help. You are completely right, once I
have fixed the cputable everything worked like a charm. I have
reviewed the last git version and it seems solved there, so I wont
publish the patch in git format ( to avoid confusions)

I remember some history on this barrier. There was a race between
open via /dev/console and the tty being fully setup. Its also why
there is a temporary variable and the global is assigned at the end

Index:
hvc_console is setting low_latency unconditionally, but some clients are
interrupt driven and will call hvc_poll from irq context. This will cause
tty_flip_buffer_push to be called from irq context, and it very clearly
states it must not be called from IRQ when low_latency is specified.

find_min_common_depth was checking the property length incorrectly.
