Let's try this one again.

I was about to say that, actually I just fired off a note started last night during a change window that I failed to hit send on. to say that. I have an Aspire 3623NWXMi. I just posted a patch to PR 98171 that addresses ACER Aspire ACPI problems. The embedded controller in the ACER Aspire models responsds rather slowly. My patch adds tunables (not to be confused with sysctl variables) that can be set at boot time to tune the FreeBSD ACPI implementation to work better with your computer. The patch pretty much fixed my problems. By pretty much, the temperature sensors fail to respond only occasionally instead of the battery and temperature sensors being totally hosed. Secondly, I believe that Acer uses Microsoft's ASL compiler which produces buggy AML. You can find fixed ASL code at acpi.sourceforge.net. The Intel ASL compiler, used by FreeBSD is less forgiving of buggy code, not to mention the ASL was probably buggy from the get-go. You may need to fix it or even replace it with a DSDT from acpi.sourceforge.net. I think the first place to start is to apply the patch from PR 98171. Play with the nobs in loader.conf a bit and if it solves your problem, great, otherwise you may need to replace your DSDT by loading a custom DSDT at boot time. Check /boot/defaults/loader.conf for the syntax. Hope this helps. It helped me. -- Cheers, Cy Schubert <Cy.Schubert@komquats.com> Web: http://www.komquats.com and http://www.bcbodybuilder.com FreeBSD UNIX: <cy@FreeBSD.org> Web: http://www.FreeBSD.org BC Government: <Cy.Schubert@gov.bc.ca> "Lift long enough and I believe arrogance is replaced by humility and fear by courage and selfishness by generosity and rudeness by compassion and caring." -- Dave Draper
