Hi,
I've periodically seen the following LOR when trying to repro a
panic after restarting my network configuration:
:lock order reversal:
1st 0xc4142f1c rtentry (rtentry) @ /usr/src/sys/net/routec:362
2nd 0xc3d08604 if_afdata (if_afdata) @ /usr/src/sys/netinet6/scope6.c:417
KDB: stack backtrace:
db_trace_self_wrapper(...)
_witness_debugger(...)
_rw_wlock(...)
in6_setscope(...)
in6_purgeaddr(...)
in6_control(...)
ifioctl(...)
soo_ioctl(...)
kern_ioctl(...)
ioctl(...)
syscallenter(...)
syscall(...)
Xint0x80_syscall()
I don't have a full backtrace or core for this. This was running
r224948 UP with WITNESS.
Thanks,
-Garrett
