--- Comment #19 from Christian Vilhelm <christian.vilhelm@xxxxxxxxxxxxxx> ---
The problem was introduced with this patch :
commit 7c237c5f6d5c62724ccd82aecdcd1fd9bd71dc75
Author: Xiangliang Yu <yuxiangl@xxxxxxxxxxx>

    [SCSI] mvsas: fixed timeout issue when removing module


The offending line :
    (MVS_PHY_ID << TXQ_PHY_SHIFT)
was before :
    (sas_port->phy_mask << TXQ_PHY_SHIFT)

Reverting the patch corrects the problem for me (kernel 3.18.1)
