Your problem seems just that gdb does not find the file chardriver.o, which is probably inside the guest (you say that in the mail). Gdb has no special access to files inside the VM. Btw, since you have a .o module I assume you are _STILL_ using a 2.4 UML kernel, right? -- Inform me of my mistakes, so I can add them to my list!
