Well, yes, it suroprised me too :-) Admittedly I dont have a very big samle set - I nly have one Ryzen box and a pair of Epyc boxes in Azure. but I cant make it run on any of them. I take the same OS and run it on Intel and its fine (literally I am cross-mounting /usr/sr and /usr/obj and doing an installworld on the Intel machine - its the same build). Will try and get this onto a USB key and test further though, so that I know the enivironment is the same. > BTW, I forgot about the patch. If nothing happens, I will commit it > today. Ah, thankyou, that would be great. -pete.
