Changed in linux (Ubuntu Natty): status: Fix Committed → Fix Released ---------end quote ------------------------------- Another post in that discussion says the fix was already pushed out to Oneric. alizard@terrarium:~$ uname -a Linux terrarium 2.6.38-10-generic-pae #46-Ubuntu SMP Tue Jun 28 16:54:49 UTC 2011 i686 athlon i386 GNU/Linux alizard@terrarium:~$ My desktop runs Natty, got the regular update upgrading the kernel to 38-10 and appears to be running several degrees cooler. Did not observe this in detail, as I was far more concerned about my netbook which is running 5 C hotter than usual. My netbook will be upgraded ASAP, the rest of you might want to try upgrading to a current kernel version and see if you still have the problem. YMMV and good luck.
