Re: debugging question
Thats what I already said in my email :) I was hoping that there is some way to dump the codepath of the kernel. Or is it maybe possible from ddb to move the context of a certain process and trace from there? Mark ps. I have narrowed it down already a bit more and hope to come with a bug report on -current in the coming days.
