I have been running the same kernel (without any changes reverted) and XHCI DEBUG on since the time of my last email. I unfortunately wasn't able to reproduce the issue and it didn't happen naturally so far. I appreciate your help but I don't want to take more of your time with an unreproducible bug. I will let you know as soon as I manage to reproduce it and grab more data. Regards, Adam
