I added compile fixes with #71. Only trivial fixes due to kernel cleanups.

I am using Rocky Linux 9.
uname -a
Linux dev1 6.1.29-1.el9.elrepo.x86_64
I am compiling using your modified linux-6.1-fixes.
su - root
cd exanic-software
git checkout linux-6.1-fixes
make -j32
make install
modprobe exanic
Whenever I run exanic-config xxx, the machine restarts.
exanic-config exanic0
Has anyone encountered a similar issue and can help me?

I tested with 6.1.15 on debian and there were no problems...
Do you see any OOPS (maybe when running modprobe from a tty) or can you add a serial console to log kernel output?

I've seen this crash on exanic-config as well - but only if I enable iommu options on the kernel command line, specifically in my case, "iommu.passthrough=0 intel_iommu=on"
Crash looks like:

I have the same crash on AMD system even if I pass amd_iommu=off in kernel parameters.
