The problem definitely occurred using bonnie++, from the "Writing
intelligently" phase ownards : e.g. opening a new tab in the Gnome
Terminal did not work and a "Terminal is not responding" window
appeared.

Title:
Desktop freezing while SSD under heavy load
Status in linux package in Ubuntu:
Incomplete
Bug description:
Every time my SSD is under heavy writing load (e.g. copying large
files from a USB stick, or downloading an ISO from a fast website),
the entire Ubuntu (Gnome) desktop, including mouse pointer, freezes.
My computer is an Asus UX410UAK with a Micron 1100 SSD.
guillaume@massada:~$ sudo dmidecode | grep -i UX
Version: UX410UAK.308
Product Name: UX410UAK
Family: UX
Product Name: UX410UAK
guillaume@massada:~$ cat /proc/scsi/scsi
Attached devices:
Host: scsi2 Channel: 00 Id: 00 Lun: 00
Vendor: ATA Model: Micron_1100_MTFD Rev: A020
Type: Direct-Access ANSI SCSI revision: 05
This is a recurring problem, and has always been with this machine
(including previous kernel and Ubuntu versions, at least for the past
2 years).
