Hi Drew, There's a mpt3sas fix in v5.3-rc3 for a problem that may cause an adapter firmware fault (although not sure of the exact fault state code; but it should cause a reset anyway).
If you could please test either 1) v5.3-rc2 [1] to confirm the issue happens with v5.3-rc2 but not with v5.3-rc3; or 2) or 4.15.0-60.67 (in bionic-proposed) which has the fix (so checking whether issue doesn't happen) that would be great. If that doesn't help, please continue with the great regression tip provided by Kai-Heng Feng. Thanks!
