https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=222273 Bug ID: 222273 Summary: Kernel panic (fatal trap 12) due to network related processes (igb driver) Product: Base System Version: 11.0-RELEASE Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: freebsd-bugs@FreeBSD.org Reporter: aayla.secura.1138@gmail.com Created attachment 186312 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=186312&action=edit kgdb backtrace The steps to getting it to panic are a bit elaborate, but the bug is reproducible every time: If I stop the netif service, then run dhclient on the wired network interface and in the meantime (while dhclient is sending discover messages) I perform a network related operation, such as printing the routing table, the kernel panics with Fatal trap 12: page fault while in kernel mode. FreeBSD version is 11.0-RELEASE-p1. It is a server machine: The CPU is Xeon E3-1275v6. The motherboard is Intel DBS1200SPLR, it has two Ethernet ports, both using igb driver. I tried wiring each and the panic occurs either way, but only if dhclient is run on the active (plugged in) interface. I attach the crash dump from one of the panics.
