So I'm back with some interesting results.

Test 1:
NXP LSDK 20.04 based on v5.4.3 - reordering reproduces instantly

Test 2:
net-next 5.9-rc3 with upstream defconfig and all downstream patches
imported from LSDK - hasn't reproduced in 20 hours of testing

Test 3:
net-next 5.9-rc3 with .config imported from LSDK - hasn't reproduced in
335 iterations

Test 4:
linux stable linux-5.4.y - hasn't reproduced in 137 iterations

Test 5:
torvalds v5.4.3 - reproduces instantly

Thanks,
