I just gave in to the App Store's constant nagging about upgrading to Yosemite. Aside from an unhappy Chrome, there is this kextd process that's constantly running close to 95% CPU. This results in the fan also running constantly and my battery being drained.

How can I get this kextd process to quiet down?

I just gave in to the App Store's constant nagging about upgrading to Yosemite. Aside from an unhappy Chrome, there is this kextd process that's constantly running close to 95% CPU. This results in the fan also running constantly and my battery being drained.

Things I tried but didn't work:

• removed all the .plist files
• upgraded to 10.10.1 when it came out this morning
• called Apple support who had me delete a cache file (/System/Library/Caches/com.apple.kext.caches/Startup/kernelcache/loadedkextmt.plist)

The process doesn't start straight at boot, but maybe 10 minutes later during use.
