В новом firmware для 5100-й серии, если не ошибаюсь, нет изменений. 

Но вот для stable ядер совсем недавно предложили интересный патч (он уже в mainline):
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=9180ac50716a097a407c6d7e7e4589754a922260

В след. обновление ядра, думаю, включим, - тогда на нём и попробовать можно.

Does the problem show up in ROSA R5 with all updates?
Comment 5 Eugene Shatokhin 2015-03-11 12:02:18 MSK
Closing for now. If the problem show up in ROSA R5 with all updates, please reopen.
