i'am not sure if it's also same Issue on 6.5
me at 6.0. and had lots Issues with lsi-mr3 Driver. Either sfcbd-watchdog stucked and was not killable. or got buffer errors once started a bigger punch of vms after a Host Crash.Or System just stucked after a while.
i have also LSI controller. and for me the only stable Driver was megaraid-sas. i had to disable lsi-mr3 and to enable megaraid legacy.
Since then all running fine.
May worth to check it
0x2 = STATUS CODE:CHECK CONDITION
0x5 = SENSE CODE:ILLEGAL REQUEST
0x24 = ADDITIONAL SENSE CODE:INVALID FIELD IN CDB
0x1a = COMMAND CODE:MODE SENSE(6)
if i understand this - the commands which getting tried > the controller doesn't understand them
Best regards
