During the installation of OpenBSD 7.1 amd64 release, after the network
interface was auto configured for DHCP, a repeated error message was
displayed to the screen at random times, "DMA write error! --resetting."
This prevented the network installation of the operating system on this
interface, so I worked around the problem using an USB network
interface. After I booted into the newly installed system, the error
continued to be displayed on the screen at random. Syspatch did not fix
the issue.
I installed OpenBSD 7.1-current (GENERIC.MP) #516 and the error
continues to be displayed on the screen at random.
