[1.] One line summary of the problem: USB drive errors with newer kernel versions [2.] Full description of the problem/report: I am seeing various USB drive errors while trying to use the drives with later versions of the kernel. I have tested with 4.1-rc5 and still see the issues. For instance, I am unable to successfully create a new file system on the drives. One example is "parted -l" which returns the following error: Error fsyncing/closing /dev/sdc: Remote I/O error dmesg shows the following error in this case: end_request: critical target error, dev sdc, sector 0 The errors appear with different brands and types of USB drives. After a kernel bisect, this seems to be the commit that caused the issue: 89fb4cd1f717a871ef79fa7debbe840e3225cd54 scsi: handle flush errors properly [3.] Keywords (i.e., modules, networking, kernel):
