Unable to load a custom module into linux kernel 5.10.60.

[blprasad]

Orange Pi zero ,I am working on running toxic (tox protocol) client. On an old image with kernel 3.4.113 was able to compile custom module and load it. But with latest image with kernel 5.10.60 not able to load my custom kernel module , getting following error.

" loading out-of-tree module taints kernel. module verification failed: signature and/or required key missing - tainting kernel "

 

Another problem I am facing as follows

ethernet eth0 repeatedly up/down ,I learn that this issue exists for the past few years now without any fix !!!

 

Any inputs regarding these are appreciated , thanks in advance.

This is generally a warning. Kernel taint generally means that you've done something unsavory, and it may have affected the status of a pristine kernel (such as a closed source license). You might check to see if the module actually loaded with the output of " lsmod "?

 

Regarding the Ethernet status, it looks like the OPi Zero is listed as a "supported" board, so you're welcome to post a topic in the appropriate subforum with armbianmonitor output. However, if the board has had a known issue for years, it may not be a simple fix, and unpaid devs may not have gotten to this issue yet.

Hi tparys,

 

thanks for the prompt reply, I treid to verify whether the module is loaded or not, but I could not succeed, I will try again with more prinks.

Hi tparys,
