How do I interpret dmesg errors?
by Mikech from LinuxQuestions.org on (#4Y4YJ)
Problem: I ran dmesg to see if the driver for my Hauupage Live 2 was loading (I am trying to get that to work with Linux but I do not want any help with that at this stage - or I won't learn anything). Too my surprise the thing is riddled with error messages in red on the terminal. What Iam asking is given examples of some of these errors, do they matter and if so how to fix them.
