Hi, in addition to the constant flickering when running on AC, there is a more "high frequency" flickering immediately after plugging in the AC: For some 5 to 10 seconds, the battery appears and disappears (according to upower) around once per second. There's also a short moment without battery after plugging out the AC. All this is gone after going to a kernel version without this patch applied. I did not notice unusual high CPU usage of upower on my system, however I noticed disc activity - according to iotop, upower is writing several MiB of data per minute to /var/lib/upower/ where it keeps some battery statistics. I do not know whether this is out of the ordinary.
