Hi! I'm wondering where to find information on the specific error codes mpt2sas spits out. I'm experiencing fault_state(0x5851) which is rendering my system unusable whenever I try to write to any of the WD20EARX drives. I've appended a dmesg snippet of the problem to this message. I apologize if this is the completely wrong place to ask this kind of question - I've been unable to find any information on the issue elsewhere. Thanks!
