Yesterday night I noticed (just before performing an update my conky showing high continuous writing to root. iotop -Pa shows this:- Total DISK READ : 0.00 B/s | Total DISK WRITE : 8.93 M/s Actual DISK READ: 0.00 B/s | Actual DISK WRITE: 11.06 M/s PID PRIO USER DISK READ DISK WRITE SWAPIN IO> COMMAND 112 be/4 root 0.00 B 64.91 M 0.00 % 24.34 % [kworker/u16:3] 11936 be/4 root 0.00 B 0.00 B 0.00 % 0.06 % [kworker/1:1] 28794 be/4 root 0.00 B 36.00 K 0.00 % 0.00 % [kworker/u16:1] This is after roughly 6-7 seconds, and 65 MB has already been written by that kworker thread. As I said, this was already happening before an upgrade. I ran the upgrade anyway, which upgraded linux to 3.16-2, and still got the same thing. Yes, I'm using [testing]. 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.
