We use DVD to install Ubuntu 15.04 kernel 3.18.0-8-generic version on our PowerVM system. After install, I am seeing this error "/build/buildd/linux-3.18.0/drivers/rtc/hctosys.c: unable to open rtc device" on the dmesg log...

It must be an order of operations thing: something is trying to do the hctosys before the driver is loaded. A few seconds later the driver loads and it seems fine after that.
