            Bug ID: 252863
           Summary: ipmi watchdog does not reset after being triggered
           Product: Base System
           Version: 12.2-RELEASE
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: kern
          Assignee: bugs at FreeBSD.org
          Reporter: janm at transactionware.com

On a Supermicro X11SCM-F based system, with the ipmi watchdog enabled, the
watchdog will only trigger once. After the system comes back up after a
watchdog triggered reboot the watchdog is ineffective and no error messages are
printed.

To make the watchdog work again, I have to reset the BMC by disconnecting power
from the system or issuing "ipmicontrol mc reset warm".

Output from "ipmitool mc watchdog get" after a full reset, system and BMC:

Watchdog Timer Use:     Reserved (0x00)
Watchdog Timer Is:      Stopped
Watchdog Timer Actions: No action (0x00)
Pre-timeout interval:   0 seconds
Timer Expiration Flags: 0x00
Initial Countdown:      0 sec
Present Countdown:      0 sec

Output from "ipmitool mc watchdog get" while the watchdog is running:

Watchdog Timer Use:     SMS/OS (0x44)
Watchdog Timer Is:      Started/Running
Watchdog Timer Actions: Power Cycle (0x03)
Pre-timeout interval:   120 seconds
Timer Expiration Flags: 0x00
Initial Countdown:      17 sec
Present Countdown:      14 sec

Output from "ipmitool mc watchdog get" after the system has come back up after
the watchdog power cycle:

Watchdog Timer Use:     SMS/OS (0x04)
Watchdog Timer Is:      Stopped
Watchdog Timer Actions: Power Cycle (0x03)
Pre-timeout interval:   120 seconds
Timer Expiration Flags: 0x10
Initial Countdown:      17 sec
Present Countdown:      0 sec

Attempting to reset the watchdog with "ipmitool mc watchdog reset" fails with
"Reset Watchdog Timer command failed: Node busy".

dmesg for ipmi:

ipmi0: <IPMI System Interface> port 0xca2,0xca3 on acpi0
ipmi0: KCS mode found at io 0xca2 on acpi
ipmi0: IPMI device rev. 1, firmware rev. 1.23, version 2.0, device support mask
