In this post there is some explanation about why does lsmod show -2 in 'used by' column. The idea is that the kernel config option CONFIG_MODULE_UNLOAD was not set.



But what if lsmod shows -1 only for one specific module while CONFIG_MODULE_UNLOAD is set in my current kernel? How to debug this muddle?

  • Does /sys/module/<module>/refcnt exist for that specific module? If so, what does it contain?

A module reference count of -1, visible both in /sys/module/<module>/refcnt and in lsmod’s output, means that the module is currently unloading.



If a module’s reference count stays at -1, that indicates a problem — dmesg should tell you more.

This Kransekake is a traditional Scandinavian baker's confection. Confectionery is the art of making confections , which are food items that are rich in sugar and carbohydrates. Exact definitions are difficult. [1] In general, though, confectionery is divided into two broad and somewhat overlapping categories, bakers' confections and sugar confections.
