I use r208975 and the following kernel config: <snip> include GENERIC ident VIMAGE nooptions SCTP options VIMAGE options BREAK_TO_DEBUGGER </snip> When doing a 'ifconfig epair0 create' the whole machine hangs (no I/O, no ping). A backtrace after breaking shows: db> bt Tracing pid 2135 tid 100124 td 0xfffff800045f9270 uart_intr() at uart_intr+0x1ac intr_event_handle() at intr_event_handle+0x5c intr_execute_handlers() at intr_execute_handlers+0x8 intr_fast() at intr_fast+0x68 -- interrupt level=0xc pil=0 %o7=0xc0088ff8 -- -- fast data access mmu miss tar=0x127d2a000 %o7=0xc03d7d40 -- mtx_init() at mtx_init+0x134 epair_modevent() at epair_modevent+0xe4 module_register_init() at module_register_init+0xdc linker_load_module() at linker_load_module+0xbd8 kern_kldload() at kern_kldload+0xd0 kldload() at kldload+0x60 syscallenter() at syscallenter+0x268 syscall() at syscall+0x74 -- syscall (304, FreeBSD ELF64, kldload) %o7=0x102fe0 -- userland() at 0x408c2028 user trace: trap %o7=0x102fe0 pc 0x408c2028, sp 0x7fdffffd8e1 pc 0x104504, sp 0x7fdffffda11 pc 0x102510, sp 0x7fdffffe291 pc 0x40226f54, sp 0x7fdffffe351 done >How-To-Repeat: >Fix: >Release-Note: >Audit-Trail: >Unformatted: _______________________________________________ freebsd-bugs@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-bugs To unsubscribe, send any mail to "freebsd-bugs-unsubscr...@freebsd.org"
