There are some PCI root bridge issues still unresolved, but they usually
cause the machine to reset instead of hanging.

You could try a kernel with DIAGNOSTIC/DEBUG/LOCK_DEBUG added (slow!), and
see if this catches anything. Do you have a special workload to trigger the
hang?

No, is it even possible on that hardware?

Also make sure you have Julian's latest changes to dev/tda.c, it will make
an audible difference on Blade 1000/2000.
