Oh hai! I've made a bugzilla issue [1] about it, but I'm not sure if anyone reading bugzilla reports, so duplicating here. I have raven ridge APU (2400g) + ASUS A320M-K motherboard and boot (4.16.4 & 4.17-rc2) hangs printing many `[ 0.001000] AMD-Vi Command Buffer Timeout` messages. With IOMMU disabled (either via EFI/BIOS or using amd_iommu=off) it boots fine.
What info is needed to debug/fix it? [1] https://bugzilla.kernel.org/show_bug.cgi?id=199513 //wbr ojab _______________________________________________ iommu mailing list [email protected] https://lists.linuxfoundation.org/mailman/listinfo/iommu
