Since I can't save myself the two reboots, I will most likely try without the usual Hyper-V and VMware host loads and just try to create the vmdk and see what happens. So I would say no, I'm not changing any settings or configuration, just trying to do "normal" things like create disks, although they are much bigger than anything I've created before. I do have a 50TB LU for the Hyper-V hosts, but never tried to create any disk that big on it. If I have time I'll try it on a Hyper-V VM as well.

I had to ask.

A with-kmem-flags coredump will be very useful.

Thanks,

p.s. r151014 is coming soon. I'll be curious if it manifests the same (mis-)behavior.  Not a lot of comstar fixes from upstream.
