They have the latest BIOS (3.0a) and BMC controller (2.19.0) firmware. I run a custom kernel with the IPMI driver compiled in, detected as follows: kernel: ipmi0: <IPMI System Interface> port 0xca2,0xca3 on acpi0 kernel: ipmi0: KCS mode found at io 0xca2 on acpi kernel: ipmi0: IPMI device rev. 1, firmware rev. 2.19, version 2.0 kernel: ipmi0: Number of channels 3 kernel: ipmi0: Attached watchdog >Description: The FreeBSD watchdog causes the BMC controller to reboot every 20-30 minutes, logging this in the system log: kernel: ipmi0: KCS: Failed to read command kernel: ipmi0: KCS error: 09 where the error number varies. At this time, the virtual USB keyboard that the BMC provides for the remote console disappears and reappears as well. There are otherwise no ill effects on the running FreeBSD system. >How-To-Repeat: Start the watchdog service (/etc/rc.d/watchdog start) and wait 30 minutes. System load has no effect. It can be an idle server or running heavy duty. >Fix: Do not run watchdog, or disable IPMI driver, or both. As a side not, I notice that watchdog does not run on any of my systems that do not have IPMI. This probably should be mentioned in the watchdog(8) man page. >Release-Note: >Audit-Trail: >Unformatted:
