I have a fix for this and have confirmed that "kgdbts" continues to work after I fix it. Running it also found splats similar to what I fixed for "kgdboc" in commit 81eaadcae81b ("kgdboc: disable the console lock when in kgdb"). I'll att a commit to my next version to move that fix into the kgdb core and then remove it from "kgdboc". I'm not setup to use kgdb over EHCI so I'll just fix that so it compiles and trust that it continues to work. For now I'll hold up on sending a new version to await feedback on v1. If I don't hear anything after a little while I'll send a v2 with just these fixes. -Doug
