Thanks for advice! I completely missed the fact that version is newer because I
saw same 3.122 number; actually in-kernel is version 3.122 and elrepo has
3.122n, and this "n" makes a lot of difference.

I tried it, according to changelog it includes fix

    tg3: Fix tg3_get_stats64 for 5700 / 5701 devs

    tg3_get_stats64() takes tp->lock when dealing with non-serdes bcm5700
    and bcm5701 devices.  However, functions that call tg3_halt() have
    already acquired tp->lock.  When tg3_get_stats64() is called in
    tg3_halt(), deadlock will occur.

which exactly resolves my problem.

This fix is dated Feb 28, sad that Red Hat maintainers have missed it in their
version :(
But at least I have the solution now.
