The gdb in base, when used against a live kernel or crash dump, is supposed to be able to backtrace individual threads via the kvm proc and kvm pcb commands. Is anyone actually using these on 5.9 or -current? If so, which archs?
I ask as I see some "this can't work" logic between the kernel and gdb for at least i386 and possibly others and I'd like to hear what *is* working that I should verify I don't break when making changes... Philip Guenther
