The above working patch has been merged in linux-4.1.y branch of linux- stable repository as can been seen here: https://git.kernel.org/cgit/linux/kernel/git/stable/linux- stable.git/log/?qt=grep&q=mmc%3A+core%3A+Enable+runtime+PM+management+of+host+devices&h=linux-4.1.y
Since Ubuntu 15.10 comes with Kernel version 4.2, I guess using Ubuntu 15.10 would fix the issue. I would wait for 14.04.4 to come out in Feb 2016 with updated kernel as depicted here: https://wiki.ubuntu.com/Kernel/LTSEnablementStack#Kernel.2BAC8-Support.A14.04.x_Ubuntu_Kernel_Support And then upgrade to Ubuntu 16.04 LTS. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1488426 Title: High CPU usage of kworker/ksoftirqd Status in HWE Next: New Status in linux package in Ubuntu: In Progress Bug description: kworker consuming 71.5% cpu resource ksoftirqd consuming 28.9% cpu resource It leads to power consumption issue and sometimes leads to BT does not work.
