I have tried these options in the config, but with same results (unstoppable dump and crash): makeoptions DEBUG=-g options WITNESS options WITNESS_KDB options KDB options KDB_TRACE options DIAGNOSTIC options KDB options DDB options GDB options INVARIANTS options INVARIANT_SUPPORT options DEBUG_LOCKS options DEBUG_VFS_LOCKS I haven't tried debugging via serial port, however. And the problem can be reproduced on ext2fs volume of any size. Next step would be original GENERIC config.
