Please let me describe the issue here.
The test case is:
- Unload module with script "sudo ./sof_remove.sh" ,
- reload module with script "sudo ./sof_insert.sh"
After several rounds of removing and inserting kernel modules, system will complain like below: "BUG: unable to handle kernel paging request at 000000292a282031"
Did you try some kernel debug options? It might show what went wrong.
No, I haven't. I'm not sure which options I can use for this case. Could you please give me some suggestions?
BTW: I have enabled DEBUG_DEVRES. Are there any other options I can try?
