Hi, I have xperia zl and yesterday accidentally magnet touched my zl...screen turned off and after that it powered on and worked but there were some errors in dmesg. Now it is randomly(or not, I think only when it is a bit overloaded) powering off but if I connect it to to pc it is not rebooting but some strange stuff appears in dmesg ( http://pastebin.com/pckHxMZF ). Any suggestions? Thanks 
Also i`m using cm11.0
UPD: Connected with adb over network and waited untill it reboots, here are last lines of dmesg
And looks like my wlan0 mac address changed

It is wifi related, maybe that`s why my mac changed
Now this is dmesg before shutting down:
