If linux emulator is compiled in, just install pkgsrc/emulators/suse_base
and run
  $ /usr/pkg/emul/bin/ls -l
and it never returns.  You may have to run `sysctl kern.sync_on_panic=1'
in advance, as panic command from DDB may be stuck.
If linux emulator is not compiled in the kernel, loading it via
/etc/rc.d/abi will trigger the lock up(probably because it runs
/compat/linux/sbin/ldconfig).

I couldn't drop in to DDB on my SMP machine, but I could on my laptop.
I'm uploading a kernel dump on my leaf account.
