【Problem description】
The watchdog timer fails to be reset on an RH2288H V3 due to timeout, as shown in the iBMC SEL.
【Problem analysis】
According to the iBMC operation logs, at 20XX-XX-26 12:39:02 the iBMC received from the OS a command for setting the watchdog timer.
201X-XX-26 12:39:02 IPMI, N/A@HOST,Payload , set watchdog timer to (RAW:04-21-03-3e-20-1c) successfully.
According to the command description, the watchdog timer is used in the OS loading phase, the timeout period is 12 minutes, the action upon timeout is Hard Reset, and NMI/Diagnostic Interrupt is configured.
iBMC 2.32 has a bug. If the pre-interrupt of the watchdog timer is SMI, NMI/Diagnostic Interrupt, or Messaging Interrupt, the watchdog timer fails to be reset.
【Solution description】
The watchdog timer on the OS side is normal. The problem is solved by upgrading the iBMC to 2.40 or later.
