The IRQ init structs are marked as __initconst which means this memory can be free after init. On this platform, the PCI IRQ init happens very late _after_ the kernel already freed the memory allocated for these structs. During IRQ allocation, the allocation function is passed with invalid data at this point leading to following error: [ 0.000000] SoC: Qualcomm Atheros QCA9533 ver 2 rev 0 [ 2.382828] Freeing unused kernel memory: 264K [ 34.414816] pci 0000:00:00.0: no irq found for pin 1 and [ 0.000000] SoC: Qualcomm Atheros QCA956X ver 1 rev 0 [ 2.125401] Freeing unused kernel memory: 284K [ 9.526479] pci 0000:00:00.0: no irq found for pin 1 After this patch: [ 14.960814] pci 0000:00:00.0: using irq 40 for pin 1 Commit318e19ba67("ar71xx: add v4.14 support") fixed this for the default targets already present in the source by default but forgot to remove the __initconst attribute for targets QCA953x and QCA956x which are only added later through platform patches.

This is the buildsystem for the OpenWrt Linux distribution.
To build your own firmware you need a Linux, BSD or MacOSX system (case
sensitive filesystem required). Cygwin is unsupported because of the lack
of a case sensitive file system.
You need gcc, binutils, bzip2, flex, python, perl, make, find, grep, diff,
unzip, gawk, getopt, subversion, libz-dev and libc headers installed.
1. Run "./scripts/feeds update -a" to obtain all the latest package definitions
defined in feeds.conf / feeds.conf.default
2. Run "./scripts/feeds install -a" to install symlinks for all obtained
packages into package/feeds/
3. Run "make menuconfig" to select your preferred configuration for the
toolchain, target system & firmware packages.
4. Run "make" to build your firmware. This will download all sources, build
the cross-compile toolchain and then cross-compile the Linux kernel & all
chosen applications for your target system.
Sunshine!
