[Bug 1784101] [NEW] Ubuntu partition fills automatically

[winux]

Public bug reported:

Hi

When I first updated Ubuntu 16.04.4, about 3 weeks ago, I found out being rapidly short of disk memory on the partition, and then could not even make a screenshot.
I went to the French forum and after a long search we found out that "pcie_aspm" was responsible for that.

Actually it fills up very rapidly 2 logs (the 2 last ones on the following list)
*********************
 ubuntu at ubuntu:~$ sudo du -ma --max-depth=1 /mnt/5 | sort -n

***********************
/mnt/5 is the mounting point of Ub partition (sda5) on the live key

Yesterday, after reseting the logs ...
*************************
ubuntu at ubuntu:~$ echo | sudo tee /mnt/5/var/log/kern.log

ubuntu at ubuntu:~$ sudo du -ma --max-depth=1 /mnt/5 | sort -n

1035	/mnt/5/lib
4383	/mnt/5/usr
6902	/mnt/5
***********************************

... I rebooted normally (no live key)
and after 5 mn I found out, from gparted, that my partition reached 37 Go, close to its max 39 Go
The only way to shutdown was a long press on the Power button, otherwise it was a continuing flow of error messages

A clever guy from the forum gave me the solution by adding "pcie_aspm" in the grub
I changed, on the following file, "sudo nautilus /etc/default/grub"
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
into
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pcie_aspm=off"

And it works !!! my partition never exceed 7 Go
I wanted to notify you about this important point which blocked my PC and, from the forum, I realized I was not the only one

Thanks for you action on future update
