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).
