Probably this is a bug in the 2200 driver from FreeBSD; it likely isn't freeing some resource before detaching.

comment:4 by halamix2, 5 years ago

some ids are still in use is caused in delete_unrhdr (src/libs/compat/freebsd_network/unit.cpp):

It checks if idStore->idBuffer->root_size is equal to 0 and panics if it's not.

idBuffer is a radix_bitmap* (headers/private/kernel/util/RadixBitmap.h), and while it is set to non-zero value during creation (radix_bitmap_create at src/system/kernel/util/RadixBitmap.cpp), root_size never changes, so it will always be bigger than 0.

Indeed; I've removed the check in hrev54081. Thanks for investigating, halamix2! Sorry for not noticing sooner.
