https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D206613 Bug ID: 206613 Summary: dhcpcd 6.10.1 crashes the 10.2-RELEASE kernel. Product: Base System Version: 10.2-RELEASE Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: freebsd-bugs@FreeBSD.org Reporter: g_amanakis@yahoo.com CC: freebsd-amd64@FreeBSD.org CC: freebsd-amd64@FreeBSD.org dhcpcd 6.10.1 and more specifically [6b2a5402c4] causes a kernel panic on FreeBSD 10.2 when starting a VNET iocage jail. The system runs a GENERIC ke= rnel with VIMAGE and IPSEC enabled. Reverting this resolves the problem.=20 /var/log/messsages: 3 Jan 24 19:30:42 x3200 kernel: vnet0:1: link state changed to DOWN 4 Jan 24 19:30:42 x3200 kernel: vnet0: link state changed to DOWN 5 Jan 24 19:30:42 x3200 kernel: bridge1: link state changed to DOWN 6 Jan 24 19:30:42 x3200 kernel: ifa_del_loopback_route: deletion failed: = 48 7 Jan 24 19:30:42 x3200 kernel: Freed UMA keg (udp_inpcb) was not empty (= 60 items).
