I have been monitoring linux next boot and functional testing on nxp devices
for more than two week and still the problem exists on nxp-ls2088.
Do you mind checking the possibilities to revert bad patches on linux next tree
and continue to work on fixes please ?
suspected bad commit: [ I have not bisected this problem ]
