If your already in READY state, there is no reason to continue in MakeIocReady. A MESSAGE_UNIT_RESET places the card into READY state. You will see that we already issued MESSAGE_UNIT_RESET from mptbase_suspend. So it should be in READY state coming into mptbase_resume, depending on which power state you transferred to from suspend. The code you added in this patch is not required, meaning we dont need to send MESSAGE_UNIT_RESET prior to ioc_do_recovery, becuase from MakeIocReady will issue a MESSAGE_UNIT_RESET if your not already in READY. I suspect there must be something else going on if you have to issue MESSAGE_UNIT_RESET when your already in READY state. My card works fine without your patch. I did the following: # echo standby > /sys/power/state There could be issues in the firmware your using. I noticed FwRev=00060200h in the log,, which is 6.02, and over a year old. I will send out a seperate email which I will copy you to the IBM system engineer support here at LSI, should be able to assist on this issue.
