I tried defconfig the first time with no luck.
I really meant "make oldconfig": it runs the configuration script and
just ask about new options.
Maybe "exact" isn't the right word. I started with that but ran it
through menuconfig and just changed the revision from -lfs-7.6 to
-lfs-7.9.
Ah, I see. I think that when doing that, the new options take
automatically their default value (which might not be what you want).
Anyway, I think the options concerning the hardware clock are of the
form *_RTC_*. You could try:
grep RTC /boot/config-xxx
and see if ther is something weird (and/or compare the output to that of
the config file for 7.6).
