Hello, In continuation to the issue described in [1] and [2]:
Unfortunately, I still suffer from the same problem on Linux kernel v4.2.3. The problem is in detailed described in [3], in particular I see the following in dmesg: sd 6:0:0:0: [sdd] 234441648 512-byte logical blocks: (120 GB/111 GiB) sd 6:0:0:0: [sdd] 4096-byte physical blocks sd 6:0:0:0: [sdd] Write Protect is off sd 6:0:0:0: [sdd] Mode Sense: 53 00 10 08 sd 6:0:0:0: [sdd] Write cache: enabled, read cache: enabled, supports DPO and FUA ... sd 6:0:0:0: [sdd] tag#0 FAILED Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE sd 6:0:0:0: [sdd] tag#0 Sense Key : Illegal Request [current] sd 6:0:0:0: [sdd] tag#0 Add.

Any information about how to fix the problem is appreciated. > [1] http://permalink.gmane.org/gmane.linux.scsi/91997 > [2] http://permalink.gmane.org/gmane.linux.usb.general/120430 > [3] http://unix.stackexchange.com/questions/237204/ > [4] > https://kernel.googlesource.com/pub/scm/linux/kernel/git/stable/linux-stable/+blame/v4.2.3/drivers/scsi/sd.c#2446 > [5] > https://kernel.googlesource.com/pub/scm/linux/kernel/git/stable/linux-stable/+blame/v4.2.3/drivers/usb/storage/unusual_devs.h#1990 -- With best regards, Dmitry -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
