Subject: Best practice when probe fails on armed watchdog?
Date: Wed, 29 Jan 2020 18:16:19 +0100 (CET)
Message-ID: <1731064051.261328.1580318179697@webmail.strato.com> (raw)

Hi!

What is the right thing to do when a watchdog device that has been armed by the bootloader fails to probe? Should the driver

- disable the device and thus save the system from being torn down by a potentially malfunctioning watchdog, at the risk of missing issues further down the line, or
- leave it as is (even though that would most likely result in a reset), hoping that the error is either transient or that there is a mechanism in place outside the kernel that will resolve it?

Is there a best practice for this case?
