Subject: [PATCH] ipmi: rate limit ipmi smi_event failure message
Date: Thu, 29 Jul 2021 17:32:28 +0800 [thread overview]
Message-ID: <20210729093228.77098-1-wenyang@linux.alibaba.com> (raw)
Sometimes we can't get a valid si_sm_data, and we print an error
message accordingly. But the ipmi module seem to like retrying a lot,
in which case we flood the kernel log with a lot of messages, eg:
[46318019.164726] ipmi_si IPI0001:00: Could not set the global enables: 0xc1.
[46318020.109700] ipmi_si IPI0001:00: Could not set the global enables: 0xc1.
[46318021.158677] ipmi_si IPI0001:00: Could not set the global enables: 0xc1.
[46318022.212598] ipmi_si IPI0001:00: Could not set the global enables: 0xc1.
[46318023.258564] ipmi_si IPI0001:00: Could not set the global enables: 0xc1.
[46318024.210455] ipmi_si IPI0001:00: Could not set the global enables: 0xc1.
[46318025.260473] ipmi_si IPI0001:00: Could not set the global enables: 0xc1.
[46318026.308445] ipmi_si IPI0001:00: Could not set the global enables: 0xc1.
[46318027.356389] ipmi_si IPI0001:00: Could not set the global enables: 0xc1.
[46318028.298288] ipmi_si IPI0001:00: Could not set the global enables: 0xc1.
[46318029.363302] ipmi_si IPI0001:00: Could not set the global enables: 0xc1.
