Re: System freeze - with logo_saver and high CPU load

[Matthew Dillon <dillon@xxxxxxxxxxxxxxxxxxxx>]

:	Hi,
:
:	I'm running v2.9.0.68.g57eab-DEVELOPMENT on an M4A78L motherboard
:with a Phenom II 955 (quad core 3.2 GHz), however this has been happening
:for a while but it's only now that I've pinned down the circumstances.
:
:	If I have the logo-saver running and displayed on the console then
:anything that generates a high CPU load (make -j 8 buildworld in an ssh
:session from another box does nicely) will lock the system up solid when the
:logo reaches a certain point near the top right hand side. Once locked the
:system is completely unresponsive to network or keyboard, only a reset or
:power cycle will unlock it. Without the logo_saver running the system is as
:solid as a rock.

    The syscons console screen saver code in general is a real problem
    for us.  It's getting hung up on the console spin lock.  I think it
    is going to be a while before it gets fixed (it won't make the release).

    We've whacked a couple of issues related to syscons but not this one
    yet.
