A while ago I discovered that all AMD IO-APICs (in separate southbridges and in FCHs) had a bug with respect to how the interrupt delivery mode got interpreted. I am curious if the problem has been fixed in Ryzen or if it is being carried on. I would appreciate any help with testing that. The discussion of the problem and the tests I used can be found in this thread: https://mail.coreboot.org/pipermail/coreboot/2016-October/082148.html https://mail.coreboot.org/pipermail/coreboot/2016-October/082156.html If you are interested and it's not really clear how to conduct a test, please write me. Thank you! -- Andriy Gapon
