 Can you boot with PRINTK_TIME and USB_STORAGE_DEBUG enabled and send
 the logs?

 Hi again. I am very sorry, your email someway lost, probably due to
 misconfiguration of my MUA.

 I have attached new boot log, kernel(now - 3.15_rc2) is configured with
 PRINTK_TIME and USB_STORAGE_DEBUG as you requested.

 Ping. Any news on this issue? Or maybe any clues what triggers this?
 
 Unfortunately I'm not able to reproduce these errors with my HW.
 Do you have a possibility to try a different USB stick/storage?
 Does the stock EdgeRouter Lite USB stick work?
 
 When simulating some errors I noticed there's a case where the driver
 does not recover properly. I'll try to send fixes for that soon.
 But that still doesn't solve why get an error in the first place. :-(

Yep, sometimes, usually on warm reboots kernel does not recognize USB
device at all, but i thought that it could be board problem itself,
cause U-Boot lost it too.

I have tried stock USB stick - unfortunately i have got same errors :-(
