There were a couple of users who had problems with the new build system which=
 were due to the kernel version they were running with their OS's.

I didn't see any problems but I am running everything on Arch Linux so it alw=
ays has the latest kernel version.

What OS are you running for your build system and what is the kernel version =
in it?

Those things may help @Michael to figure out what the issue is.

Adolf.
