Any ideas on how to proceed? Next thing I'm going to try is downgrading linux to 3.15, but I thought I'd post this here first in case I don't make it back.
And I made it back alive. 3.15.8-1 does not have the same problem. Also downgraded bbswitch to 0.8-14, nvidia t 340.24-3, linux-headers to 3.15.8-1, virtualbox-host-modules to 4.3.14-3, vhba-module to 20140629-5, and lirc-utils to 1:0.9.0-75. Should I open a bug report? I don't think I have sufficient detail, in particular because I don't know how to track down what caused that kworker process. My system is an i7 laptop, the hard disc partitions (including root) are btrfs formatted. Previous Arch Linux bbs posts regarding kworker I/O activity is not as serious as what I'm seeing and seemed to affect ext4. Again, suggestions are appreciated.
