Hello.
Is BFQ enabled for kernel builds? I tried elevator=bfq with 4.12.rc7 and got all partitions unmountable.
On 4.12, BFQ is available as multi-queue I/O scheduler, so it's a two step enablement: - Pass scsi.use_blk_mq=1 boot option to switch to SCSI MQ. - Choose bfq in /sys/block/sd*/queue/scheduler file, e.g. # echo bfq > /sys/block/sda/queue/scheduler The latter can be automated via udev, tmpfiles.d or whatever, too.
