Hi.
Recently I reported pretty useless bug into archlinux bugtracker about system freezes caused by Apple Magic Trackpad.
https://bugs.archlinux.org/task/37587
I've been able to reproduce it and dump dmesg output to file. Now I need some help in «decoding» info from dmesg to be able to provide more info into bug ticket or even report a bug upstream
Help me decide, please, what component (hid, bluetooth, etc) causes this bug.
I'm not sure, because unloading hid_magicmouse module stops errors in dmesg. Though hci_rx_work [bluetooth] is mentioned in the log.
