Hello Ryan,

It's correct. We have seen the problem on 2 Facebook BMC platforms so far. Given the other ~10 Facebook BMC platforms are still running kernel 4.1 (with (4, 7, 7) settings), I'd assume more platforms will be impacted after upgrading to the latest kernel.

Thank you for spending time on this!


Cheers,

Tao
