https://bugzilla.kernel.org/show_bug.cgi?id=219681 --- Comment #12 from dantmnf2@xxxxxxxxx --- > is the enclosure running at SuperSpeed when it works correctly? There are some chances to work with SuperSpeed+, mostly with a longer cable. To manually trigger the issue without udisks2: echo "write through" > /sys/class/scsi_disk/0:0:0:0/cache_type smartctl -a /dev/sda dd if=/dev/sda of=/dev/null count=1 But this sequence more often gives ~30s IO delay, not timeout. Also tried another disk with this enclosure and the issue is gone. Seems the disk is to blame. As for the Realtek ethernet, I found it never enters U1/U2 state on Windows. Given there is already NO_LPM quirks for RTL8153, maybe we also need one for RTL8156? -- You may reply to this email to add a comment.
