I have a question about my Ask Ubuntu post: Ubuntu 20.04 ACPI errors after suspend: cannot release Mutex
After I realized a persistent error message, I searched for it and found the exact problem on someone else's identical system (both XPS 15s with Ubuntu 20.04). One of the answers wrote "solved:" and suggested a solution, but it did not work for me so I wrote about it. I just came back to check if there are any new solutions, but to my surprise, the answer was deleted by Ravexina. I would just like to know why.
