I accidentally checked on Kernel.org and found out that Linux Kernel 3.6.4 has been released by Greg. I downloaded this source and compiled it both on my desktop and workstation and now, i'm ready to test this shiny Linux Kernel release.
I'm still using Linux Kernel 3.6 for now and even though .4 didn't brings fixes for EXT4 corruption bug that was introduced in Linux Kernel 3.6.2 and still exists in 3.6.3, i think it's about time to upgrade to this stable release and hopefully it really stable for production machines.
Luckily, i don't have to worry about NVidia and VMWare patches, since it's not a major upgrade and things should work out of the box with those two products.
There's only one way to find out: reboot :)
