The above behavior is reproducible using upstream mainline kernel, so not Ubuntu specific.

A bisection against upstream kernel revealed :

# first bad commit: [a736e9b6a03283a2e0fc8190b748b3a672f289c1] hpsa: correct ioaccel2 sg chain len

Note that the behavior also seems to be fix in recent upstream kernel (tested with v4.14-rc2)

The upstream v4.14-rc2 kernel is using :
HPSA_DRIVER_VERSION : "3.4.20-0"

while

Ubuntu-4.4.0-97.120 is using :
HPSA_DRIVER_VERSION : "3.4.14-0"

Another bisection is in progress to find the first good commit between "a736e9b6a03283a2e0fc8190b748b3a672f289c1]" and "v4.14-rc2" HEAD.
