> Which kernel did the system use in Xenial? Can you please roll back to the older kernel and test it?
Looks like 4.15.0-99 was the last kernel I used on Xenial before the upgrade. Is it possible to use a kernel that old on focal? If so, would the bisect instructions in LP: #1798979 be sufficient to follow? Happy to give it a shot if so. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1879393 Title: Delayed failure in Genesys USB3 SD card reader Status in linux package in Ubuntu: Confirmed Bug description: I have a "UGreen USB3 Hub/SD card reader" which worked reliably under Ubuntu Xenial for many months. Recently, I re-installed the machine it was attached to with a fresh install of Ubuntu Focal. When initially booted, the device works perfectly (at least, the USB3 ports and SD card reader do; those are the only ports I use on it). However, after some period of time I inevitably find the device has stopped working, and dmesg is flooded with repeats of the following block of messages (I include several copies below so the typical time-delay between repeats can be observed): [39695.777289] xhci_hcd 0000:05:00.0: WARN Cannot submit Set TR Deq Ptr [39695.777293] xhci_hcd 0000:05:00.0: A Set TR Deq Ptr command is pending.

[39859.706965] usb 6-2.3: reset SuperSpeed Gen 1 USB device number 3 using xhci_hcd The delay before failure (and these messages appearing) is highly variable. Sometimes it's within a couple of minutes of booting the machine; sometimes the device works happily for a couple of hours before failure. I've found that simply replugging the device (temporarily) solves the issue, but obviously I'd prefer the device to be as reliable as it was under the Xenial kernel. This may be related to LP: #1798979 which features extremely similar log messages on failure, but the symptoms are ever so slightly different (no CPU spike, no blinking LED), as is the model of card reader, hence why I've filed a separate bug. I'll add an apport report after filing this, but I should add there are multiple card-readers on this machine (my work involves raspberry pis, so I often find myself re-writing cards in bulk :). The specific one with the issue is listed as follows in the lsusb output: Bus 006 Device 005: ID 05e3:0743 Genesys Logic, Inc. SDXC and microSDXC CardReader The other card reader listed in that output (realtek) is a separate device with no issues. --- ProblemType: Bug ApportVersion: 2.20.11-0ubuntu27 Architecture: amd64 CasperMD5CheckResult: skip CurrentDesktop: ubuntu:GNOME DistroRelease: Ubuntu 20.04 InstallationDate: Installed on 2020-05-09 (9 days ago) InstallationMedia: Ubuntu 20.04 LTS "Focal Fossa" - Release amd64 (20200423) IwConfig: lo no wireless extensions. eno1 no wireless extensions.
