I have Ubuntu 18.04 in two computers (the same hardware) and sometimes during the day, the led of the SSD is lighten continual for a few seconds (almost 30) and the computer practically freezes during this time, happens randomly, for example, with something simple like open
In the first place I installed Pop!_OS 18.10 but I removed it thinking that it was the problem.
Then I installed Ubuntu 18.04, but the problem continues, I also removed swap partition.
And I checked the SSD with smarttools and everything seems fine.
The SSD patitions:
Device Start End Sectors Size Type /dev/sda1 2048 1953791 1951744 953M EFI System /dev/sda2 1953792 99610623 97656832 46.6G Linux filesystem /dev/sda3 99610624 937701375 838090752 399.6G Linux filesystem
I was testing with some commands and for explame, when is failing:
sudo hdparm -t /dev/sda /dev/sda: Timing buffered disk reads: 2 MB in 16.79 seconds = 121.97 kB/sec
sudo hdparm -t /dev/sda /dev/sda: Timing buffered disk reads: 1004 MB in 3.00 seconds = 334.33 MB/sec
