Toshiba 1905S303: update

Toshiba 1905S303: update

[Erico M Mendonca]

Updating on my problem with Fn-F5 (switch video out) hanging the machine...

I recompiled the latest known kernel working for me (2.4.21-013mdk,
shipped with Mandrake 9.1) with ACPI debug, and the current DSDT table
I'm using. I do see "QUERY_1C" messages with this kernel on
/var/log/messages, whereas with a newer kernel I do not (the machine
hangs first...).

I have this in my DSDT:

                    Method (_Q1C, 0, NotSerialized)
                    {
                        Store ("=====QUERY_1C=====", Debug)
                        If (\_SB.PCI0.LPC0.EC0.VIDO)
                        {
                            PHSS (0x01)
                            Store (0x00, \_SB.PCI0.LPC0.EC0.VIDO)
                        }
                    }


So the problem would be related to EC code. Were there any significant
changes to this code that could be causing this?

When did you start to have this kind of problem?

It sounds like a regression. To let me better understand your problem, please file any
useful thing on bugzilla.kernel.org

I just created bug #1735 on bugzilla to deal with this. Please take a look at it:

http://bugme.osdl.org/show_bug.cgi?id=1735

I also posted the relevant dmesg and system log files from working and non-working situations, plus my current DSDT and the original DSDT.

Thanks a lot for that. To testing latest ACPI, you can try
bk clone ACPI testing tree located on http://linux-acpi.bkbits.net/ .
Or you can try acpi patch filed at
http://www.kernel.org/pub/linux/kernel/people/lenb/acpi/patches/.
