https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=148807 sebastian.huber@embedded-brains.de changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |sebastian.huber@embedded-br | |ains.de --- Comment #16 from sebastian.huber@embedded-brains.de --- I see this problem also with the port of the FreeBSD 9-stable (2015-04-09) network stack to the RTEMS real-time operating system (Altera Cyclone V target). It occurs quite frequently with multiple concurrent IPv4 TCP transfers to /dev/null and from /dev/zero. The stack trace is: 000|panic(fmt = 0x00636E14) 001|sbsndptr(?, ?, ?, ?) 002|tcp_output(?) 003|tcp_do_segment(?, ?, so = 0x3FF3D7C0, tp = 0x3FF2F828, drop_hdrlen = 52, tlen = 0, iptos = 0, ?) 004|tcp_input(m = 0x3FF21700, ?) 005|ip_input(m = 0x3FF21700) 006|netisr_dispatch_src(?, ?, ?) 007|ether_demux(ifp = 0x006DFEE0, m = 0x3FF21700) 008|ether_nh_input(?) 009|netisr_dispatch_src(?, ?, ?) 010|dwc_rxfinish_locked(inline) 010|dwc_intr(arg = 0x006DEA20) 011|bsp_interrupt_server_task(?) 012|Thread_Handler() ---|end of frame -- You are receiving this mail because: You are the assignee for the bug.
