Please see if kernel parameter "pcie_aspm=force pcie_aspm.policy=performance" helps.

Sometimes I can move the mouse, sometimes not. Dmesg contains soft lockups, hard lockups and MCEs. Hardware: CPU: Ryzen 7 1800X RAM: Crucial Ballistix 32 GiB DDR4 Motherboard: ASUS Crosshair VI Hero PSU: Corsair TX750v2 I have also tested with a Corsair TX750M and a Gigabyte Aorus Ultra Gaming. I've also used a different memory kit, Corsair LPX Vengeance. Still had issues. I have had the processor replaced by AMD two times. The first time because it segfaulted while executing this script: https://github.com/suaefar/ryzen-test/blob/master/kill-ryzen.sh And the second time because the processor thrown MCEs while executing that same script. Now I'm left with MCEs collected at boot or with soft and hard lockups collected by the kernel with the NMI watchdog timer. Having the extension GNOME Vitals polling hardware sensors with asus- wmi-sensors makes the freezes more frequent. This bug opened in mainline kernel's bugzilla https://bugzilla.kernel.org/show_bug.cgi?id=208201 provides a C program which can trigger errors too (unknown NMIs and PCIe AER). There are two versions: * V1 https://bugzilla.kernel.org/attachment.cgi?id=292941 * V2 https://bugzilla.kernel.org/attachment.cgi?id=292949 [41717.839567] Uhhuh.

The Crosshair VI Hero motherboard has shown dead USB ports at boot sometimes, leaving the system without keyboard and mouse and Ubuntu booting slowly.
