Yeah, IIRC it might have to be "mq-bfq"; will test immediately and report back.
The "elevator=..." thing remains the same as it used to work for quite some time now.
Indeed, something strange is going on here: # cat /proc/cmdline BOOT_IMAGE=/vmlinuz-4.12.0-2.g7c5c393-default root=... quiet scsi.use_blk_mq=1 # cat /sys/block/sd?/queue/*scheduler* noop [deadline] cfq noop [deadline] cfq noop [deadline] cfq BUT: # dmesg | grep scheduler [ 2.059289] io scheduler noop registered [ 2.059289] io scheduler deadline registered [ 2.059296] io scheduler cfq registered (default) [ 2.059296] io scheduler mq-deadline registered [ 2.059297] io scheduler kyber registered [ 2.059303] io scheduler bfq registered So, it should be "bfq", but it does not seem to be available?!? Strange... Cheers. l8er manfred
