Hmm, your kernel base version is 4.10.0-rc8 but the symbols here
look like prior to my commit, because with my commit here should
be disable_hardirq() calling synchronize_hardirq().
Did you revert it or make any local changes?
The kernel is -rc8 with reverted d966564fcdc19e13eb6ba1fbe6b8101070339c3d

No other changes..
That is weird, the stack trace doesn't match the source code for some reason.
Can you objdump your e1000.ko module to see if that is true?
