Sure,
I took the same config as before, only disabling CONFIG_RSBAC_MAC in the menuconfig. I have similar results on the 2 machines : a kernel NULL pointer dereference comes up, with a Oops, which then seems to cause a deadlock. Here are the boot logs.

Hi Terence,
I started looking into this problem, but have not found the reason yet. Since it seems to crash in the mostly obsolete MAC module code, could you please try without MAC?

Hi,
With Jean-Marc Lacroix, we have been trying to enable more options than
the
default ones for the RSBAC kernel configuration. However, the configuration we have come up with does not always boot correctly depending on the
machine we
install the kernel on. All machines are based on Debian 13, and the kernels were launched in softmode, version 6.18.7.
On the first machine, a Mac Book Pro 2011 (CPU : Intel Core i5-2415M) with SysV init and XFCE, the system comes up properly. On the second one, a HP Z240 (CPU : Intel Xeon E3-1225) with systemd, we have first tried the kernel on a Gnome install, where the boot ends up with a "kernel NULL pointer dereference" and a kernel panic. On the same machine,
where we
reinstalled a non graphical system, the same kernel configuration still produces the dereference with multiple kernel oops. On the third one, a Lenovo ThinkStation P520c (CPU : Intel Xeon W-2102)
with
systemd and no desktop environment, there also is a "kernel NULL pointer dereference" that stops the boot (and is not in the logs), but no kernel panic is displayed.
I've appended the config file along with the boot logs.
Do you have any idea as to why these problems occur ?
