Description

When I boot OI on my system, I see these debug messages on the console:

startup.c:2306: Calling configure()...
startup.c:2308: configure() done
startup.c:2329: NULLing out bootops
startup.c:2346: Enabling interrupts
ERROR: failed to attach AMD IOMMU
startup.c:2377: startup_end() done
startup.c:2520: Unmapping lower boot pages
startup.c:2539: Releasing boot pages
startup.c:2565: Boot pages released

Without debugging, the ERROR line appears on the console immediately after the SunOS banner. It's not written to the messages log. I don't notice any ill effects from this error.

My hardware is an ASUS PRIME B350M-A motherboard with an AMD Ryzen 3 1200 Quad-Core CPU. It has two 4-gig unbuffered ECC DIMMs with an ASUS HD 6450 Silent video card. Booting the latest USB image on this system requires a loader that has been patched to fix bug #8651.
