Hello,

I've just booted my laptop and found that networking was broken. Pings 
of other devices on my home network failed. A reboot has restored 
networking, but I thought I should report the problem anyway. I'll have 
no time tomorrow, but on Thursday I'll do a few boots to ascertain how 
repeatable the problem is.

Attached is a complete dmesg, but perhaps the most relevant part is:

Let me know if I can provide any additional information, although to be 
honest, the boot completed and the KDE desktop started up OK, so there 
may not be much else I can provide unless I find that the problem is 
repeatable.
