Is this a regression since 4.12? What storage >device is this? Is the device using an IO scheduler? I've started seeing this while testing on -next, so this regression started after v4.12. The fuzzer runs in qemu, the block device is the result of the "-hda" parameter to qemu. As far as I can tell this results the creation of an ATA device. >dmesg after boot and .config would be helpful, too. Attached boot dmesg and config. -- Thanks, Sasha
