Some motherboard bioses for the IXP 400 had a subtle USB 2.0 bug where high-bandwidth devices (like external hard drives) would cause the controller to "stall," requiring a reboot. This was fixed in later silicon revisions (IXP 400 B2 stepping), but early adopters suffered.
This is where the IXP 400 shines. ATI’s Catalyst 6.11 driver package contains the final and most stable southbridge drivers. Look for the version 6.9 or later. ati ixp 400

The ATI IXP 400 was a pioneering network processing unit that played a significant role in shaping the network infrastructure of the early 2000s. Its high-performance packet processing, integrated security features, and flexible programmability made it a popular choice among network equipment providers. As network processing demands continue to evolve, the legacy of the ATI IXP 400 can be seen in the development of next-generation NPUs and the ongoing innovation in the network processing space.

Surprisingly good! The Linux kernel (5.x and 6.x) has excellent support for the ATI IXP 400 via the pata_atiixp and ahci drivers. Ubuntu 22.04 LTS will boot and run, but expect poor 2D/3D acceleration from the integrated graphics (that’s the northbridge’s problem, not the IXP).
