Not a git-kernel nerd, but just an ordinary kernel nerd. :) |

The kernel RTC driver creates /dev/rtc0 and then I assume udev creates |
9 |
/dev/rtc from there, so if you are missing rtc0 that's a possible |
10 |
source of the problem. Which would coincide with your kernel upgrade. |

I know 3.9 introduced a couple new RTC-related option so maybe it |
13 |
changed around some more to 3.10 series. I would run menuconfig and |
14 |
see what it thinks you have enabled in that section, just in case |
15 |
something got lost in transition from one kernel to the next. |

In dmesg on my non-git 3.9.4 kernel it looks like: |

I'm using the "PC-Style CMOS" RTC driver, and I have all of the |
27 |
RTC-related options enabled except for the debugging options. |
