Is there any remedy for this? Using grep to move around works but is annoyingly cumbersome and time consuming.
I don't see any obvious problem with the bits you posted and without a reproducable test case it's hard to say what the actual problem is.
One problem could be that you have some declaration/proclamation somewhere, e.g. (proclaim '(optimize (debug 0))). If you're using SBCL and debug is 0 then SLIME can't find the definition for a name. I have (proclaim '(optimize (debug 2))) in my .sbclrc and that seems to work quite OK.
Another cause could be that you load the source and not the fasl file. M-. does typically not work so well for non-compiled functions.
Yet another problem could be that there is no IN-PACKAGE form in the file so that SLIME searches in the wrong package. (That's unlikey, tho, as compiling an individual function seems to work.)
In general, M-. seems to be used by many people therefore I think we would note regressions on our side pretty quickly.
