Hi! I use several SuperMicro boxes with intergrated IPMI card. http://www.supermicro.com/products/system/1U/5016/SYS-5016T-MTF.cfm FreeBSD 8.2 sometimes hang in the past after panics so I use IPMI's watchdog and generally it works nice with 5 minute timeout. The card is detected as following: ipmi0: <IPMI System Interface> on isa0 ipmi0: KCS mode found at io 0xca2 alignment 0x1 on isa ipmi0: IPMI device rev. 1, firmware rev. 1.07, version 2.0 ipmi0: Number of channels 2 ipmi0: Attached watchdog Sometimes ipmi driver issues "KCS errors" to system logs that I ignore as they seem harmless. However, one of my boxes suddenly rebooted with watchdog after following errors written to console: ipmi0: KCS: Reply address mismatch ipmi0: KCS error: 01 ipmi0: KCS: Reply address mismatch ipmi0: KCS error: 01 ipmi0: KCS: Command mismatch ipmi0: KCS error: 01 ipmi0: KCS: Reply address mismatch ipmi0: KCS error: 01 ipmi0: KCS: Reply address mismatch ipmi0: KCS error: 01 ipmi0: KCS: Command mismatch ipmi0: KCS error: 01 ipmi0: KCS: Reply address mismatch ipmi0: KCS error: 01 ipmi0: KCS: Reply address mismatch ipmi0: KCS error: 01 ipmi0: KCS: Reply address mismatch ipmi0: KCS error: 01 ipmi0: Failed to reset watchdog ipmi0: KCS: Command mismatch ipmi0: KCS error: 01 It seems, the driver lost ability to contact IPMI watchdog timer and that was the reason of reboot. What can be done to avoid such resets in the future? Eugene Grosbein
