ACPI - console problems 2.4.4

ACPI - console problems 2.4.4

[Nick Papadonis]

Is anyone having problems with ACPI causing console problems in kernel
2.4.4 w/ Intel's patches?   When watching my system boot over the
serial console, things work fine.  When looking at my VAIO-FX140's
LCD, my console no longer updates after ACPI starts initializing _INI methods.

I am able to login and shutdown without my LCD echoing back.

Here is my output from the serial port:

Generally a good rule is 'dont bother with ACPI'. But do let Andrew Grover
know how it fails on your box

My VAIO doesn't support APM. :(

I was trying to understand the call path on _INIT.  Hopefully with
some printk's I can track down the problem.

Any direction or areas for me to examine?  Thanks.

Is this vanilla 2.4.4? I somehow doubt that.

Yes it is, however with Intel's ACPI patches.

I suspect there is a problem with the VGA adapter + ACPI.  I haven't
been able to use ACPI at all because of this.

Is there ANYONE out there that has a VAIO?  It would be nice if
someone could reproduce this too.
