Thanks for the report, very appreciated. There were no significant
change to the i2c-i801 driver between kernel versions 3.14 and 3.16, so
something else must have fixed it. If we knew which commit that was, we
could backport it to stable kernels. So if you have the expertise and
time to kill, it would be wonderful if you could bisect the kernel from
3.14 to 3.16 to find out the commit that fixed the problem (beware that
git bisect assumes you are looking for a regression, not a fix, so bad
will mean good and good will mean bad.) If you can't, no worry, your
success report was already very valuable.
The only change specific to the Intel 5400 chipset I could find during
that timeframe was:
commit c2e650c49a1795238895a474873a12c6c5662833

i5400_edac: Disable device when unloading module
but I very much doubt this is related.
Thanks,
