I just upgraded my Linux kernel and had major suspend issues due to the XHCI driver. I ended up having to disable the ability for XHCI to wake my machine. On fedora cinnamon, I was getting random freezes on resume, and momentary freezes on resume on Linux Mint. Disabling the ability for XHCI to wake my machine fixed it. This sleep() looks like bad code designed to work around a race condition. Perhaps it's related to the issue I had. This issue was the worst Linux issue I've had in ~10+ years. (I'm on ryzen first gen cpu)

I'm having similar issue with my Ryzen laptop. May I know what you had to change to disable XHCI wakeup?

  Thankfully, I have a repo of all the little configs and scripts I have used. You can do cat /proc/acpi/wakeup to see what is allowed to wake your machine. Echoing the device ID into /proc/acpi/wakeup will toggle it between disabled and enabled. So to disable XHCI wakeup, I had to do: sudo echo XHC0 > /proc/acpi/wakeup Now that will reset on every boot, so I wrote a systemd service to do it on startup, and instead of just disabling 'XCH0', I found another user online that had written a shell script to disable everything's ability to wake the machine. This is the systemd unit to disable the ability for devices to wake the machine: https://github.com/jknightdoeswork/dotfiles/blob/master/disable_acpi_wake.service https://github.com/jknightdoeswork/dotfiles/blob/master/disa... This is the shell script to install that systemd unit so it runs on every boot: https://github.com/jknightdoeswork/dotfiles/blob/master/install_disable_acpi_wake_service.sh https://github.com/jknightdoeswork/dotfiles/blob/master/inst... Note that with this installed, I'm pretty sure the only way to wake your machine is to press the power button. I prefer that but you might not. You may want to disable _just_ the XHCI devices, not _all_ of em. Up to you. Feel free to ask more questions.
