Well, the actual time doesn't matter - I use this monolithic kernel on both virtual machines as well as a physical server. Up until 3.13.x this arrangement worked flawlessly, now for 3.14.x - everything will be the same except me using BTRFS... > So without an initrd and with btrfs compiled into the kernel I'd expect to see > Btrfs loaded before 12.4 seconds. Is this an SSD? Or HDD, or hardware raid?

I will try to provide these, but it will have to wait for tomorrow as currently my monolithic kernel .config does not support serial ports, so I will have to reconfigure, recompile both 3.13.x and 3.14.x to test them and provide the requested data. > > Also can you post a diff of the config file for the working 3.13.11 and not > working 3.14.1 kernels? The requested diff was posted earlier, reattaching once more. --------------------------------- Plamen Petrov
