[08:35] <alkisg> cking: hi, after longs hours of testing, the slow disk writes issue appears in all 32bit systems with 16+ gb ram. Now I'm trying to bisect it, and I'm at "after 15.04=3.19, before 15.10=4.2"
[08:35] <alkisg> cking: did you manage to find something related that I could test, instead of bisecting?
[08:37] <cking> alkisg, there have been some changes that I am aware of, I need to find the exact commit and and inform you of the kernel where the behaviour changed
[08:43] <alkisg> E.g. would diff -R <3.19>/proc/sys/vm vs <4.2>/proc/sys/vm and playing with the settings there help?
[08:55] <alkisg> Xenial with 3.19 works, /me reboots into xenial with 4.2 to verify it's broken there...
