Edit subr_autoconf.c and set the number of threads to 1. int interrupt_config_threads = 8; int mountroot_config_threads = 2; Or you can patch them in ddb with boot -d Also you can add DEBUG_AUTOCONF in current, which prints the name of the deferred driver as well as the count ot the deferred mutex. For even better success, boot -1 christos
