Dear MIPS porters,
DSA would like to upgrade the remaining mips*el buildds to bullseye (and
later to bookworm), however we have trouble running the Bullseye or
Bookworm kernel on the LS3A-RS780-1w ones.
Both Bullseye and Bookworm kernels boot fine up to the userland, but the
network card does not work. It *seems* to an interrupt issue as the
corresponding counter in /proc/interrupts does not change, and in
addition the kernel logs show the following warnings:

Any idea how to solve this issue? I have attached a full 6.1 kernel boot
log for reference.
asking on linux-mips@vger.kernel.org might get more feedback on the issue...
From the quick look at kernel code and device tree of the board IMHO
the DTS is missing interrupt mapping entries for the PCI bus.
Could someone from Loongson have a look at the issue ?
