Hi Imperia, I built a mainline kernel (version 4.16) with a different quirk that I think might help here. Can you test it? Thanks in advance!
Instructions (run all as root): 1) wget people.canonical.com/~gpiccoli/imperia416.tgz 2) mv imperia416.tgz / 3) tar -zxf imperia416.tgz 4) update-initramfs -c -k 4.16.0-imperia+ Now that's important: if you have access to some serial console in the machine (or if you have physical access), you can reboot into this new kernel. In case _you only have ssh_, I'd suggest to remove the kernel boot entry from grub, and boot through kexec for safety reasons: a) Remove boot entries from grub.cfg (you can copy away vmlinuz-4.16-imperia+ to some place outside /boot and run "update-grub" for this) b) apt-get install kexec-tools c) kexec vmlinuz-4.16-imperia+ --initrd initrd.img-4.16-imperia+ --append="$(cat /proc/cmdline)" ---- After machine (hopefully!) boot to the new kernel, check in dmesg if the quirk is there: #$ dmesg|grep QUIRK [0.813486] QUIRK: XHCI_AVOID_BEI If you can see that output ("QUIRK: XHCI_AVOID_BEI"), then the quirk was applied. Now, just need to try to reproduce the issue again.
