Hello Paolo, I installed this version of bfq-mq on a server that boots from a SATA disk. That server boots fine with kernel v4.10-rc7 but not with this tree. The first 30 seconds of the boot process seem to proceed normally but after that time the messages on the console stop scrolling and about another 30 seconds later the server reboots. I haven't found anything useful in the system log. I configured the block layer as follows: $ grep '^C.*_MQ_' .config CONFIG_BLK_MQ_PCI=3Dy CONFIG_MQ_IOSCHED_BFQ=3Dy CONFIG_MQ_IOSCHED_DEADLINE=3Dy CONFIG_MQ_IOSCHED_NONE=3Dy CONFIG_DEFAULT_MQ_BFQ_MQ=3Dy CONFIG_DEFAULT_MQ_IOSCHED=3D"bfq-mq" CONFIG_SCSI_MQ_DEFAULT=3Dy CONFIG_DM_MQ_DEFAULT=3Dy Bart.
