I'm new to linux, but have some experience with scientific computer on unix based systems. I've recently put LM14 w/ MATE on a thinkpad x230.
It's been mostly enjoyable, but I get a few errors here and there. Most of them seem common, or sub-common, and I've been able to make some progress by searching the forums. But I have a few that show up on shutdown that I don't even know where to start with, and I hope the forums could help.
Posted below is a image of the screen (i've been unable to find the logfile for these) of what appears when I shutdown while running on battery power. This screen is from if I simply halt the computer from terminal, but the same errors appear on full shutdown (just not long enough to take a picture of them).
I was having some problems shutting down, which ended up being related to laptop-mode-tools, which is the reason I initially captured that image. But, even when I remove laptop-mode-tools, and then later, after reinstalling it and configuring it in a way that solved my shutdown problem, the same errors are persistant.
When shutting down with AC power plugged in, I receive some, but not all of the errors posted above. If we number the errors 1-8 from top to bottom, I recieve only 1,2,6, & 8 when shutting down with AC power plugged in.
I recognize enough to know that, these errors are related to the ethernet, wifi, and sound card. Of those devices I have only encountered problems with my sound card, which seems to be software based, and occurs after waking from suspend. This particular problem seems to be fairly common, and I've found some leads on that by forum searching. Anyways, not being able to use my internal speakers after resuming is a pretty low priority problem.
So, to summarize. I would like to know/fix the cause of these errors, or, failing that, know that they are not indicitive of more serious problems. Thanks for any help you can provide!

I guess my primary concern is whether or not these errors are indicitive of potential, present, or future damage to my computer. Obviously, no errors is always a goal, but if the errors are trivial, than I'm not going to spend tons and tons of time solving them, especially since I'm not seeing any problems with my wireless or ethernet, at least not currently.
