In this mail it mentions:
echo 120 > /sys/block/sda/device/timeout
It seems to have stabilised the system.
I noticed recently that my USB devices like my mobile phone mount as

What is the best way to set the timeout to 120 permanently at boot-up as
is done with echo 120 > /sys/block/sda/device/timeout manually?
