This is an OpenPGP/MIME signed message (RFC 2440 and 3156) --------------enig88EA98E593F43FE117E55494 Content-Type: text/plain; charset=ISO-8859-15; format=flowed Content-Transfer-Encoding: quoted-printable Dear coders, I recognized one RELENG_8 problem when trying to shutdown via serial=20 console. While shutdown via SSH works like expected, when called via=20 serial console it keeps hanging forever. I compiled a debug kernel for my embedded device and got the following=20 backtrace: ~KDB: enter: Line break on console [thread pid 1102 tid 100074 ] Stopped at kdb_enter+0x3b: movl $0,kdb_why db> bt Tracing pid 1102 tid 100074 td 0xc36c26c0 kdb_enter(c08aca1d,c08b61ae,d5c5e894,c35a0180,0,...) at kdb_enter+0x3b uart_intr(c35a0100,c36c26c0,c344a900,c347b0d0,4,...) at uart_intr+0x298 intr_event_handle(c344a900,d5c5e8ac,c36c26c0,c37a9ad0,1ce,...) at=20 intr_event_handle+0x4b intr_execute_handlers(c347b0d0,d5c5e8ac,0,d5c5e90c,c0852ed4,...) at=20 intr_execute_handlers+0x48 lapic_handle_intr(38,d5c5e8ac) at lapic_handle_intr+0x3a Xapic_isr1() at Xapic_isr1+0x34 --- interrupt, eip =3D 0xc05d0814, esp =3D 0xd5c5e8ec, ebp =3D 0xd5c5e90c= --- _lockmgr_assert(c37a9ad0,1,c08d41d6,1ce,d5c5e940,...) at=20 _lockmgr_assert+0x13e __lockmgr_args(c37a9ad0,100000,c37a9aec,0,0,...) at __lockmgr_args+0x16b vop_stdunlock(d5c5e9ec,0,c36c26c0,80000,c37a9a78,...) at vop_stdunlock+0x= 55 VOP_UNLOCK_APV(c0912b40,d5c5e9ec,c091d71c,c09477e0,c37a9a78,...) at=20 VOP_UNLOCK_APV+0x9a _vn_lock(c37a9a78,80100,c08d4ec2,823,c08c5fec,...) at _vn_lock+0xbc vget(c37a9a78,80100,c36c26c0,4f3,c37a9a78,...) at vget+0x61 devfs_revoke(d5c5eaa4,d5c5eaa4,c08c2b09,157,c36cf330,...) at=20 devfs_revoke+0x210 exit1(c36c26c0,1,c08c78e8,ab6,3,...) at exit1+0x9ff sigexit(c36c26c0,1,c08c78e8,a49,0,...) at sigexit+0x84 postsig(1,64,c08cc013,df,c36cf2a8,...) at postsig+0x34d ast(d5c5ed38) at ast+0x42f doreti_ast() at doreti_ast+0x17 I have no idea where the problem is, nor how to get more info.
