1)Sticker on the TP-Link box says "Version 1.10"
2)It's a custom PC (parts from all over the place), so it has no
"sticker" or something similar.
3)I hadn't tested the particular device on previous
kernels/installations on this PC. The device works as expected on
machines with USB 2.0 ports.
4)Cannot boot into a live environment (no CD drive), and the PC cannot
boot via USB (doublechecked BIOS settings, and also tried to boot from a
couple of verified working USB images).
I installed the latest upstream kernel (4.17.0-041700-generic), booted
normally, inserted the USB but the problem still persists (lots of dmesg traces
and a 100% load that makes the system almost unresponsive). According to the
instructions, I am marking the bug "Confirmed" and adding the tag
"kernel-bug-exists-upstream".
** Changed in: linux (Ubuntu)
Status: Incomplete => Confirmed
** Tags removed: bionic needs-upstream-testing
** Tags added: kernel-bug-exists-upstream
