I have not had a single "bad removal" when running on a RedKernel and CM11 for 2 months (as tested with SD Card Monitor). RedKernel: http://forum.xda-developers.com/lg-g...ernel-t2856297
When I flash a "vanilla" kernel from any recent CM11 the errors are immediately back, usually when the tablet stays in deep sleep. Unfortunately, I have had also this issue with the new Lollipop from this thread: http://forum.xda-developers.com/lg-g...rx21m-t2941207
Actually the RedKernel is very good. I use v9 because on v10 I had strange battery drain during sleep. The only problem I have encountered is related to WiFi switching: when I move to a different network it does not re-connect automatically and the WiFi is unresponsive. The only way to fix it is to switch to the Airplane Mode and back., but while it works fine with the known networks it has some problems scanning for the new ones. It can be quite irritating while travelling for instance.
p.s. my sd card is exFAT formatted
