Dear developers,
I have a Icybox 4 HDD enclosure with a JMicrom JMS567 SATA to USB converter.
When the device is under load and more than 1 hardrive is acessed, the USB
enclosure frequently restarts. This leaves often a corrup filesystem. I tried
to switch off UAS by creating a file in /etc/modprobe.d/blacklist_uas.conf with
the following content:
options usb-storage quirks=152d:0567:u
This disables UAS, and I did not exerinecs restarts of the box. But of course
thios laves only USB speeds on the USB3 connector, which is quite slow.
I think this suggest this is a kernel bug and not a hardware issues.
I aasume the problem is in the linux-image-4.15.0-33-generic package.
Similar has been reported:

Any help would be greatly appreciated.
Best regards
Michael
