See attached dmesg. (There are also a number of additional WARNs and BUGs that occur after the hardware is reset.)

I did not encounter this issue on vanilla 4.14.xx kernels; I only encountered this issue after upgrading from the 4.14 to 4.19 LTS series.

Should be fixed by https://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next.git/commit/?id=3baf7528d6f832b28622d1ddadd2e47f6c2b5e08

Please cherry pick this on 4.19. if it works, we'll send the patch for inclusion in 4.19 branch.
Comment 2 Emmanuel Grumbach 2019-01-17 05:03:40 UTC 
FWIW: I sent the fix to Greg to be included in 4.19. Didn't get any answer yet.
