The errors I was getting were different from yours, although I got IMB marriage errors, they were always followed by 2 other errors as well.
In my case the issue was a small network cable (3rd one down) on the back plane module needed to be replaced - that fixed it.
Per what you have above it seems to indicate that "586" is front or side cover.
Personally i'd remove those switches (not completely, just so you can access them) spray some deoxit in them and see if that helps.
But it does seem to indicate its a switch issue for you.
