Basically I would like to get kernel backtrace of a bunch of threads

I would like to run kgdb, collect kernel backtrace of specific threads

get the stack trace.
Have a look at /usr/sbin/crashinfo for an example of how to do so -
basically just run kgdb $KERNEL $VMCORE < commands_file.
procstat -kk [pid] will give a kernel stack trace from userspace.
