[Bug 264257] [tcp] Panic: Fatal trap 12: page fault while in kernel mode (if_io_tqg_4) - m_copydata ... at /usr/src/sys/kern/uipc_mbuf.c:659

--- Comment #63 from Dmitriy <supportme@ukr.net> ---
(In reply to Michael Tuexen from comment #62)

Option was added to sysctl.conf, system rebooted, after reboot it definetly was
checked:
sysctl net.inet.tcp.tcp_pcap_packets
net.inet.tcp.tcp_pcap_packets: 10

Going to set net.inet.tcp.tcp_pcap_packets=30 for sure. Waiting for new core.

Offtop: meantime kernel was rebilt without INVARIANTS to continue running
without panicing, but logging. Hope results would be helpful too:
