Hi Matt, Yes, it would require an svn up to head and buildworld+buildkernel. Alternatively, there are snapshots available on the FTP server that include the change. Yet another alternative, for now, if you're feeling adventurous enough to cherry-pick the patch, the relevant patch is r277314, or a simple drop-in of the sys/dev/iicbus/adt746x.c from head would work (still have to compile from source, but everything is 10 except this file). I'm in the process of creating a patch to be included in 10.2, which you could upgrade to at release time as well. - Justin On Thu, Jul 9, 2015 at 1:38 AM, Matthias Schojohann <matthias.schojohann@gmail.com> wrote: > Hey Justin, > i'm not quite sure what you mean with "can you try with head"? > Like svn head and make buildworld etc.?! > After my disastrous upgrade to 11.0 i don't know if i want to again :D > > Cheers, Matt > > 2015-07-09 5:35 GMT+02:00 Justin Hibbits <jrh29@alumni.cwru.edu>: >> >> On Wed, Jul 8, 2015 at 8:12 PM, Justin Hibbits <jrh29@alumni.cwru.edu> >> wrote: >> > On Wed, Jul 8, 2015 at 7:13 AM, Matthias Schojohann >> > <matthias.schojohann@gmail.com> wrote: >> >> Hey all, >> >> i have a FreeBSD10.1-RELEASE on my iBook G4 1,41GHz and every once in a >> >> while i get an error on the terminal that says: >> >> WARNING: Current temperature (CPU BOTTOMSIDE: 255.0 C) exceeds critical >> >> temperature (80.0 C); count = 1 >> >> >> >> sysctl dev.adt746x.0.sensors.cpu_bottomside.temp however gives me temps >> >> like 50.0 C so where does my system get the 255 from?
