The latest snapshot probably already has those fixes. But if you get the same output, please try again in a day or so. In case you're interested, the problem is that the kernel virtual address space is somewhat limited in the current implementation (4G, which I now bumped to 6G). With 128G a large fraction of that space gets used for the data structures that describe the memory pages. I need to expand the kernel virtual address space further but that is a bit more work. > It is a new build so I'll be trying a few different things on it before > putting it into serious use.

If you end up testing additonal PCIe hardware in the machine let me know and I can provide some hints for adding the necessary drivers. Cheers, Mark
