From ca8c1c53b03b3b1aef5a6efdab7f1af86be0e6d7 Mon Sep 17 00:00:00 2001 From: Wen Yang Date: Thu, 29 Jul 2021 17:32:28 +0800 Subject: ipmi: rate limit ipmi smi_event failure message 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.
