my hardware is a core 2 quad 9550, 6gb ram, gigabyte ep45-ds4, radeon 5870, ssd, hd, realtek sound and ethernet.

I installed Lion last year, kept fakesmc and plugins up to date, and chameleon, and applied lion updates when they were released.  i have a fully functional dsdt with speedstep enabled.  Time Machine would automatically back up across my network to a time capsule every hour.  Recently I noticed it wasn't backing up automatically anymore - it stopped sometime after about March.  It would still backup manually, but came up with this log message when trying to backup automatically

'com.apple.backupd: Not starting automatic backup due to thermal level'

I just installed Mountain lion and get the same message, plus an 'error 102' message.

I also installed ML on another machine with an acer motherboard, nvidia graphics, different sound, intel ethernet. and got the same problem.  The only things that I can think were the same were fakesmc and chameleon.

After tearing down my time capsule I discovered the problem was local when trying to auto-backup to a hard drive attached to the sata ports.

I've tried - rolling back chameleon, fakesmc, using a different smbios.plist, mac pro 5,1 and 3,1, removing agpm kext.  

I'm about to reinstall lion 10.7.0 just to see if that works.  Also I could try employing nullcpupm?

Does anyone know whats going on here?  Googling these error messages comes up with very little.  (5 hits)

All I can think is that somewhere around 10.7.3 apple added some thermal sensing to lion which breaks this - but no one else has reported a problem?

Thanks for your help.

it happens when you go from 10.7.3 to 10.7.4.  Any idea what sensor its looking for and how to spoof it?

I´m having the same problem on Mountain Lion:

Aug  8 19:35:00 taruga.home com.apple.backupd[645]: Not starting automatic backup due to thermal level.

Same for me on Mountain Lion... :-(

Found out the problem in my case was because of ssdt.aml

So what was wrong with your ssdt? Maybe your solution could help us fix ours, too.

I don´t know what the problem was, all I know is that it messed with time machine backups with that '

Not

starting automatic backup due to thermal level

.'

So, I just deleted my ssdt.aml file and all is fine now
