https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=293127 --- Comment #11 from yuan.mei@gmail.com --- (In reply to Mark Johnston from comment #9) I ran GENERIC-DEBUG kernel for a few days. The machine went into a deadlock state (had to hard reset) and did not generate a dump. However, in an old dmesg save, there's the following message. Not sure if this is relevant. lock order reversal: 1st 0xfffffe00c4489a00 tcphash (tcphash, sleep mutex) @ /usr/src/sys/netinet/tcp_usrreq.c:1529 2nd 0xffffffff822e8ae0 in6_ifaddr_lock (in6_ifaddr_lock, rm) @ /usr/src/sys/netinet6/in6_src.c:293 lock order tcphash -> in6_ifaddr_lock attempted at: #0 0xffffffff80c0eb21 at witness_checkorder+0xbe1 #1 0xffffffff80b8dc79 at _rm_rlock_debug+0x129 #2 0xffffffff80de61fd at in6_selectsrc+0x3fd #3 0xffffffff80de5d9d at in6_selectsrc_socket+0x6d #4 0xffffffff80de3861 at in6_pcbconnect+0x291 #5 0xffffffff80dc6877 at tcp6_connect+0xb7 #6 0xffffffff80dc41f5 at tcp6_usr_connect+0x2f5 #7 0xffffffff80c4f500 at soconnectat+0xc0 #8 0xffffffff80c577d1 at kern_connectat+0xe1 #9 0xffffffff80c576c1 at sys_connect+0x81 #10 0xffffffff810eb979 at amd64_syscall+0x169 #11 0xffffffff810bd36b at fast_syscall_common+0xf8 Limiting icmp ping response from 193 to 192 packets/sec The machine has been rebooted and running the GENERIC-DEBUG kernel again. Will see what happens. -- You are receiving this mail because: You are the assignee for the bug.home | help
