There are several things failing on the tegra124-nyan-big, at
least I've isolated one with my latest bisection run:

6c78935777d12ead2d32adf3eb525a24faf02d04 is the first bad commit
commit 6c78935777d12ead2d32adf3eb525a24faf02d04

     video: fbdev: Convert timers to use timer_setup()

These boot tests are with multi_v7_defconfig with CONFIG_MODULES
and CONFIG_DRM_NOUVEAU disabled:

* the first one on the revision mentioned above, fails:

* then the same but with the commit reverted, passes:

This was found using the still experimental automated bisection
tool for, I'm not sure yet how reliable the results
are.  I think the manual check with these 2 boots proves it, but
I haven't really investigated further than that.

So I then did the same tests at the top of the branch, on the
next-20171113 tag:

* next-20171113, fails but differently:

* next-20171113 with the commit reverted, still fails:

It's hard to tell whether the commit I mentioned got fixed
in-between, I guess it would be best to not have any boot failure
in any case.

The next thing I'll try is start a bisection for the other
failure see on next-20171113 tag, with the commit above reverted
and see if it leads anywhere...

Hope this helps!
