Sure, I'll bring things up to speed tomorrow. In the meantime, the fact that disabling ASLR makes your problem disappear *is* indicative of TLB problems, it means that when you end up accessing the wrong address space the page you're after happens to be mapped (with ASLR, you're more likely to fault). You might want to check how much you've miscompiled :) Will _______________________________________________ kvmarm mailing list kvmarm@xxxxxxxxxxxxxxxxxxxxx https://lists.cs.columbia.edu/cucslists/listinfo/kvmarm
