What is a watchdog timer panic or error message?

On SCO systems, this is apt to indicate a problem with the Intel Pro100 nic card driver; see https://aplawrence.com/cgi-bin/ta.pl?arg=109718

In general, a watchdog timer is a piece of code that attempts to keep some other piece of code from getting stuck in an endless loop. Usually that's done by some common data structure that the code being watched is supposed to update frequently. The watchdog code keeps checking; if it sees that the data has not been updated, it assumes the other program has gone awry.

Many of the products and books I review are things I purchased for my own use. Some were given to me specifically for the purpose of reviewing them. I resell or can earn commissions from the sale of some of these items. Links within these pages may be affiliate links that pay me for referring you to them. That's mostly insignificant amounts of money; whenever it is not I have made my relationship plain. I also may own stock in companies mentioned here. If you have any question, please do feel free to contact me.

Specific links that take you to pages that allow you to purchase the item I reviewed are very likely to pay me a commission. Many of the books I review were given to me by the publishers specifically for the purpose of writing a review. These gifts and referral fees do not affect my opinions; I often give bad reviews anyway.
