Same issue here on a new 16.04 install on a new HP laptop. SSD. It was crashing randomly during the install, then when I got it installed it crashed every time I tried to run the updater.
Setting the vm.dirty_ratio and vm.dirty_background_ratio to 10 and 5 worked for me as well .... so far. I did notice one interesting thing, which I feel might help diagnose what's going on behind the scenes. When I was having the problem, the CPU temp would get pretty high (up to 70 C) and the fan on the laptop was running very loudly. These symptoms happened every time. The mouse became slower, and slower, and unresponsive. Ctrl-Alt-F1 and other keyboard shortcuts were unresponsive as well. After changing those vm values, I was able to go through the updater with no issue. And my CPU temp was about 10 C lower, hovering around 60 during the updater. The cooling fan did not go on high either. So somehow the higher vm.dirty values are creating a situation where the CPU is working much harder than it needs to for the job it's trying to do. I don't know nearly enough about the inner workings of linux to know what this means, but my instincts tell me it might be an important clue for anyone trying to fix this bug. Hopefully it helps. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to nautilus in Ubuntu. https://bugs.launchpad.net/bugs/1208993 Title: Ubuntu slows down and hangs while copying file from/to USB Status in nautilus package in Ubuntu: Confirmed Bug description: Hi While copying many and large files to and from a USB drive, the system becomes incredibly slow and sometimes hangs.
