It seems that the latest changes (last 7 days) introduced this problem:
...
run_interrupt_driven_hooks: still waiting after 60 seconds for xpt_config
run_interrupt_driven_hooks: still waiting after 120 seconds for xpt_config
run_interrupt_driven_hooks: still waiting after 180 seconds for xpt_config
run_interrupt_driven_hooks: still waiting after 240 seconds for xpt_config
...

i'll try to hunt this down, but any help is welcome.
