So gnumach faults while loading the ELFs, before ever jumping to userspace? And the addresses seem well above the 4 GB limit; so this is probably with Luca's latest patchset. I have not tried that, so no, it does not ring a bell, sorry. Maybe try what I've been doing: without that patchset but with the BRK_START hack. That seems to have worked for Flavio too, judging by the commits in the cross-hurd repo. Sergey
