I've added some AMD people to Cc. Suravee, Tom, any ideas here? One of the screen-shots behind the link below show IOTLB_INV_TIMEOUT errors, so it is likely ATS related. Maybe you guys can reproduce it on your side?Thanks, Joerg On Thu, Apr 26, 2018 at 10:28:47AM +0000, ojab // wrote: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?
I realize this is an Asus system, but what BIOS version is on it? Did you look to see if an update is available (which I suspect is not, given that RR is quite new).
Have you made Asus aware of the problem? Gary _______________________________________________ iommu mailing list [email protected] https://lists.linuxfoundation.org/mailman/listinfo/iommu
