Work around is to install older kernel:

sudo dnf install -y kernel-4.18.0-408.el8.x86_64.rpm kernel-devel-4.18.0-448.el8.x86_64 kernel-headers-4.18.0-448.el8.x86_64
sudo reboot

sudo dnf -y remove kernel-tools-4.18.0-490.el8.x86_64 kernel-modules-4.18.0-490.el8.x86_64 kernel-tools-libs-4.18.0-490.el8.x86_64 kernel-4.18.0-490.el8.x86_64 kernel-core-4.18.0-490.el8.x86_64 kernel-devel-4.18.0-490.el8.x86_64

sudo vim /etc/dnf/dnf.conf
exclude=asterisk kernel*

Thanks for reporting this. DAHDI is currently broken on newer kernels due to Sangoma's incompetence at maintaining it. I suggest you file a complaint with Sangoma sales and technical support about this. You're not going to get any official help here.

You could also try installing DAHDI using PhreakScript[1], which has a ton of compiler fixes that don't exist upstream. I'm not sure if this one is present though yet; if not, we'll try to get that fixed.

You also might want to give https://gitea.osmocom.org/retronetworking/dahdi-linux a try. It is known (and continuously verified to build against) kernel v4.19. As your target (v4.18) is not far from it, so you might be lucky.

@push143smart This issue was resolved by merge of a759a57 and can be closed

a759a57 seems to only fix for version 6 kernels, not 4.18.0-xxx on RHEL 8.8/AlmaLinux/RockyLinux.
Add #define netif_napi_add netif_napi_add_weight to kernel.h without the ifdef.
