Looking at the DSDT link posted, those variables are never set in it. I wonder who, or what, is expected to set them then... Perhaps it would be worth experimenting instead with OSI when booting and see what happens then? e.g. acpi_osi="!Windows 2006" (Perhaps OSYS also triggers an SMI trap which does or doesn't do it? Worth a shot at least). > Best you create a bug for that at bugzilla.kernel.org (and add me to CC > or post the bug no). > Full (or none) fan is a real blocker bug that should generally be > resolved. I've also had a report from a user the other day that hit the same bug on an Aspire 5710 series (which seems to have the same root cause, from glancing over the DSDT): http://aceracpi.googlecode.com/svn/trunk/dsdt/acer/aspire/5710.dsl > Does this BIOS expose an ACPI fan device correctly? Acer BIOS's never expose the fan, AFAIK (and it's not available through WMI either). -Carlos -- E-Mail: carlos@xxxxxxxxxxxxxxxxxxx Web: strangeworlds.co.uk GPG Key ID: 0x23EE722D -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
