Bug ID: 215025
Summary: Panic in arptimer
Product: Base System
Version: 11.0-STABLE
Hardware: amd64
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: wireless
Assignee: freebsd-wireless@FreeBSD.org
Reporter: boris.astardzh...@gmail.com

Hello,
Ever since after upgrading to releng/11 I've been experiencing issues with my
ThinkPad R500's Intel wireless card which in fact used to work flawlessly in
10.x. Basically I'm unable to associate or rather it happens to associate
pretty slowly - 10+ minutes. Here's the card as reported by pciconf:
iwn0@pci0:3:0:0: class=0x028000 card=0x12118086 chip=0x42378086 rev=0x00
hdr=0x00
vendor = 'Intel Corporation'
device = 'PRO/Wireless 5100 AGN [Shiloh] Network Connection'
class = network
After upgrading to stable/11 due to unrelated reasons - commit
763ff62bcd42458bcc338e1ee34bd76e46f1a393 I experienced the following panic
which I think is related to my wireless card:
