Hello. Still chasing this bug.
I posted some time ago some debugs and was asked to clean them up and try again.
So, I re-coded my debug.
The messages are below and the code change follows.
======================
( 1 ) handle_transaction_done: smi cmd:0x2c does not match the smi cmd:0x06
in response
( 2 ) handle_transaction_done: smi netfn:0x07 does not match user data
cmd:0x2d
IPMI message handler: BMC returned incorrect response, expected netfn 2d cmd 0,
got netfn 7 cmd 35 msgid:0
handle_transaction_done: smi cmd:0x06 does not match the smi cmd:0x2c in
response
handle_transaction_done: smi netfn:0x2d does not match user data cmd:0x07
IPMI message handler: BMC returned incorrect response, expected netfn 7 cmd 1,
got netfn 2d cmd 0 msgid:1
======================
It appears the command and response in SMI message do not match what is in the
user data.
I hope this is helpful.
