Bug Description

RTC device doesn't appear in /dev, and various other symptoms indicate absence of RTC device

root@vmhost2:~# lsmod | grep rtc

root@vmhost2:~# dmesg | grep rtc
[ 1.992386] platform rtc_cmos: registered platform RTC device (no PNP device found)
[ 2.122900] /build/buildd/linux-2.6.27/drivers/rtc/hctosys.c: unable to open rtc device (rtc0)

root@vmhost2:~# hwclock -w --debug
hwclock from util-linux-ng 2.14
hwclock: Open of /dev/rtc failed, errno=2: No such file or directory.

I suspect the Ubuntu kernel is lacking some of the very recent upstream patches that (maybe) resolve this issue.

This appears to be fixed (at least in my case) with linux-image-server 2.6.27-11
