+Subject: [PATCH] powerpc: fix early exit from udev on hotplug event for fadump
+
+Sysfs /sys/kernel/fadump/hotplug_ready contains 1 if hotplug is
+supported by fadump.
+
+Now to exit early the RUN command should grep 0 from
+/sys/kernel/fadump/hotplug_ready instead of 1.
+
+Fix it by updating RUN command.

+Subject: [PATCH] 99-kdump.conf: Omit nouveau and amdgpu module
+
+Resolves: https://issues.redhat.com/browse/RHEL-52304
+
+The GPU module provides no significant utility in second kernel, and it
+introduces firmware that occupies lots of memory, which is critical in
+the constrained environment of kdump. Omit it helps reduce memory usage
+and optimize the crash recovery process.

+Subject: [PATCH] 99-kdump.conf: Omit hwdb dracut module
+
+The hwdb (udev hardware database) file `/etc/udev/hwdb.bin` is currently
+included in the initramfs, taking up approximately 13MB of space. This is
+a significant size for kdump initramfs, which may lead more OOM issues.
+
+Certain advanced device initializations that rely on hwdb (e.g., custom
+keyboard mappings, specific touchpad configurations) may not work in the
+kdump environment.
+
+However, kdump do not require hwdb in the most cases, as critical devices
+like storage, network, and basic input devices are typically handled by
+standard udev rules and kernel drivers.
+
+This change prioritizes reducing initramfs size over retaining hardware
+database functionality, as the latter is rarely critical in the kdump
+environment.
