Dear Linux folks,
On the Dell OptiPlex 5055 with AMD Ryzen 5 PRO 1500 and UEFI firmware
1.1.20, setting ASPM from *Disabled* to *Auto* in the firmware menu,
Linux 5.5 continuously logs the messages below.
```

```
Is that a firmware bug, or can this be worked around in the Linux kernel?
Kind regards,
