One thing I do when gdb isn't useful, and I know where I want to stop, is put a 'printk("something\n"); while(1) ;' there, and just run UML with no debugger. When it stops: if you're using skas mode, just attach gdb to it if you're using tt mode, do the following kill -STOP the 'R' UML process kill -9 the tracing thread attach gdb to the -STOPped process Either way, you've got your stack trace.
