Yes. It's just that on hurd-amd64 we don't have the choice :) > I want to try to update rumpkernel sources, to add better hardware support in > rumpdisk, and then we can test if the problem keeps in the new version. I don't think a newer upstream version would change anything: freebsd has been working fine for a long time. Missing proper memory wiring (e.g. perhaps the contiguous allocator) is a much more probable culprit. Simplest would probably be to just *observe* what is happening, from the kernel debugger, to check what rumpdisk is stuck on. Rather that making all sorts of guesses that can take a much longer time to check. Samuel
