However, at some point, the KCS is unable to reach the IPMI controller. Typical error is: ipmi0: KCS: Reply address mismatch ipmi0: KCS error: 01 ipmi0: KCS: Reply address mismatch ipmi0: KCS error: 01 ipmi0: Failed to set watchdog over an undetermined period of time. Sometimes it stops before the watchdog triggers, sometimes it [falsely] triggers the watchdog. - Arnaud [0]: I'll have a look to the physical machine and let you know.Received on Fri Oct 21 2011 - 19:31:03 UTC
