Public bug reported:
On my Lenovo X61s, WLAN randomly stops working, typically after a few hours of
running time. I don't know any remedy but to reboot.
This behavior started maybe 2 or 3 months ago. My maching is usually kept up to
date, so the problem might be caused by some kernel update at that time.
The relevant part in dmesg (attached) starts with
