An *addition* to the workaround suggested by the original poster, for my use case I disabled the autosuspend feature (that causes the reset according to the logs). This seems to work fine around the problem:
# echo -1 >/sys/module/usbcore/parameters/autosuspend With this option, I don't longer have the sound interruptions when playing music from the disk. The modules options for the workaround looks like this: $ cat /etc/modprobe.d/usb3-disk-bug.conf # Get uids from lsusb -b => Id Vendor:Id Product:u # update-initramfs -u options usb-storage quirks=0x0bc2:0xab20:u options usbcore autosuspend=-1 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1584557 Title: Seagate external drive causes SCSI bus resets when UAS enabled To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1584557/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
