Hi, there is some bug in (most probably) netgraph code. I did fresh csup and rebuild today. Whenever I try to turn bluetooth on (equivalent to plugging in the dongle), panic occurs:
ubt0: <Micro Star International product 0xa97a, class 224/1, rev 2.00/31.64, addr 2> on usbus3 panic: in /usr/src/sys/modules/netgraph/netgraph/../../../netgraph/ng_base.c:634 ng_make_node_common() vnet=0 curvnet=0 cpuid = 0 This does not occur with kernel from sources three days old.

Now I recompiled kernel again, this time without options VIMAGE in config, and panic does not occur. So the original problem is INIT_VNET_NETGRAPH implementation in presence of options VIMAGE in kernel config. If anyone has anything to test, please let me know.
