Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.20 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

I am also seeing this with current Linux (5.7-rc7) on an MSI B350M MORTAR and a Dell OptiPlex 5055. Both are AMD Ryzen systems, so this seems to affect all of those.

The IOMMU subsystem maintainer responded to report this issue to the mainboard vendor, so they fix the firmware [1].

Everybody experiencing this, please contact the mainboard vendor to fix this. I already did, and the more contact them, the higher it will rise in their ticketing system.

[Paul Menzel (paulmenzel)]

It’d be great if Canonical also used their Dell and AMD contacts to get this fixed.

[Paul Menzel (paulmenzel)]

Just a note, on the Dell OptiPlex 5055 Ryzen CPU/0P03DX, BIOS 1.1.20 05/31/2019 (AGESA SummitPI-AM4 1.0.0.7a) I am only seeing the interrupt warning. Performance counters are supported there.
