SSD Instability under Linux

SSD Instability

I was having some serious instability with my new SSD under Linux. Installation with LMDE was not possible and Ubuntu kept on locking up when copying files.

It seems that the HD is too quick and the native queuing of commands can cause instability; disabling this has made my machine more stable and I have not noticed any deterioration in performance.

Add libata.force=noncq somewhere on the Linux line of your currently kernel in the grub config file.

sudo pluma /boot/grub/grub.cfg

menuentry "Ubuntu (on /dev/sda1)" --class gnu-linux --class gnu --class os {
	insmod part_msdos
	insmod ext2
	set root='(/dev/sda,msdos1)'
	search --no-floppy --fs-uuid --set=root xxxxxxx
	linux /boot/vmlinuz-3.5.0-23-generic root=UUID=xxxxxxxx ro quiet splash libata.force=noncq $vt_handoff
	initrd /boot/initrd.img-3.5.0-23-generic
}

More information about libata.force-noncq can be found here.

Also you can add this into a live disc or current grub boot prompt but pressing the tab or | key. A screen shot is shown below.
