@mattmattox ah yes the "ubuntu-ism". There is something with Ubuntu and compiling the kernel that's different from other distributions. ATM we check if the kernel is 6.10 and we adapt the CFLAGS for the newer kernel. This works for Fedora and Arch, which it was tested on, but as it seems not for Ubuntu 24.10. This is not a total surprise.

Atm I'm having some issues getting Ubuntu 24.10 into the test environment, as the cloud-image is not behaving as expected. The fix will probably be to have the CFLAGS change based on what the kernel build scripts have configured.

@mattmattox you can use the rerethunk branch for now. The main issue is that arch and fedora are not happy at module init, though ubuntu 24.10 seems perfectly fine with it. I've removed the CFLAG that caused it in this branch. Once I have a fix for fio_init_driver to not thunk on the other two I'll push that in here and that will end up in main.
