[Vaio SZ5MN] Unable to Power-off

[Alexey Tarasov]

Hello,

I've VGN-SZ4MRN, FreeBSD 8.0-CURRENT. There is also same problem, i've
solved it by switching off lan power before power off.

For this purpose I'm using modified acpi_sony (sources are here:
dodologics.ru/20080425_acpi_sony.tar.bz2)
before switching off i'm making: sysctl hw.vaio.power_lan=0; shutdown -p now

And it powers off correctly. As far as I know SZ5 is much similar to SZ4, so
it may help you also.

Best regards,
Alexey

PS:
If you don't want to use these sources (it also adds some events
notifications, partial SPIC support and thus may be unstable), you may add
line

{ "lanp", "GLNP", "LNPW", "Lan power"},

before last line in acpi_sony_name_list struct in acpi_sony.c:

{NULL, NULL, NULL}

It'll add handling of "get lan power" and "set lan power" ACPI methods for
SNC. Sysctl oid will be named as other usual acpi_sony oids (something like:
dev.acpi_sony.0.lanp). I'm sure it also must work (cause in modified sources
it makes exactly the same).
