https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D278389 Bug ID: 278389 Summary: kernel panic, kernel core generated from ipfw_chk() function, patch given was not working Product: Base System Version: Unspecified Hardware: amd64 OS: Any Status: New Severity: Affects Some People Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: bkeertha@cisco.com We have observed kernel crash from ipfw_chk() function. Given patch https://reviews.freebsd.org/D31484, is not working in 11.2 free= bsd, we are still seeing the kernel panic.
