Hi Jerry, The Debian kernel team received a number of reports over the past few years of instability of the Proliant DL380 G7 and DL380p G8, seemingly related to the hpwdt driver (in that this goes away if it is not loaded). These reports can be seen at <https://bugs.debian.org/898336>. The instability has been seen with kernel versions ranging from 4.16 to 6.1.y, including after the backport of commit dced0b3e51dd "watchdog/hpwdt: Only claim UNKNOWN NMI if from iLO"). I can see that hpwdt seems to be used for error reporting so it's not clear to me whether these are problems caused by the driver, or the driver is only reporting that something bad happened. Do you have any ideas about what's going wrong here? Is there something odd about these models that needs to be handled in hpwdt, or are they just popular models?
