--- Comment #34 from Andreas Osterburg ---
I can confirm this issue, too. I have two large Supermicro-Servers which freeze
with enabled IOMMU after a few hours. This started when I upgraded to 42.3. The
last kernel of 42.2 did not freeze. So a working update would be a great idea.
For the interested, here are the last words of one of them:
