I'm getting an SE Linux error on boot
A kernel problem occurred, but your kernel has been tainted (flags:POE).
Explanation:P - Proprietary module has been loaded.
O - Out-of-tree module has been loaded.
E - Unsigned module has been loaded.
Kernel maintainers are unable to diagnose tainted reports. Tainted modules:
wl.
This error message is pretty clear. You are using a non-standard kerner
driver. Capsule summary: this voids your Linux warranty, in a manner of
speaking. Kernel lockups cannot be diagnosed with an out-of-tree driver
crammed into it.
A Google search indicates that "wl" is a Broadcom wireless driver. It's
unlikely that you've been running the same exact kernel version for all the
years you've said you had no issues. You must've been updating kernels all
along, and doing whatever is needed to recompile the wl driver for each new
kernel version. So the most likely answer, based on all available facts, is
that the wl driver is no longer compatible with the current Fedora kernel,
or exhibits a bug under it.
Perhaps you can try updating the wl module, with the current kernel. Or try
booting the previous kernel, and see if the lockups go away.
