Bug ID: 231659
Summary: 12-ALPHA6 r338900 crashes with IPsec on network load
Product: Base System
Version: CURRENT
Hardware: amd64
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: kern
Assignee: b...@freebsd.org
Reporter: l...@freebsd.org
I'm running network benchmarks with IPsec in transport mode. It is simple
"iperf3" run after setting up IPsec with "setkey".
Network adapter is igb (I210).
Here is backtrace
