Description siyia 2018-02-04 19:37:06 UTC 
Hello, disk manager cannot mount and/or sometimes detect properly my usb drives under kernel 4.15, whereas under kernel 4.14.15 everything works fine.Disk manager hangs when trying to mount a detected usb drive in an infinite loop and i cant eject it or reboot the system,unless i hard reset.

Additional info: i use mq-bfq for all drives
Comment 1 siyia 2018-02-05 14:42:22 UTC 
I pinpointed the problem down to the mq-bfq scheduler,with default cfq scheduler everything works as expected.
