No I didn't realise it was necessary :)

Yes it is :-)

So, you need to add these lines in your kernel (I assume it's still the GENERIC otherwise use your existing config),

After recompiling and rebooting, you can check the dmesg if the ds1307 driver is loaded, otherwise invoke "kldload ds1307" and see if it's detected. Add a line into your /boot/loader.conf with ds1307_enable="YES" if necessary. Lastly, kindly backup your data before recompiling for safety.

Thanks.


You're welcome.
 

I chatted to some people on IRC and I think it's fixed in a later version anyway with these commits:
https://cgit.freebsd.org/src/commit/?id=1bd3e8ba696633ccd7525030d951b58ade167814
https://cgit.freebsd.org/src/commit/?id=a534b50e245d801af887d91b5d48ebcf120aa039


Wow, this is good news...
 
Although I have not been brave enough to update to HEAD and try it yet :)

Yeah, better to wait than meet a lot of surprises with HEAD :-)

Thanks for the fix. I hope to try it soon.
