Created attachment 616188 [details] sgiseeq driver patch Netbooting the kernel sys-kernel/mips-sources-4.19.79::gentoo on Indigo2 Impact 10000 machine shows sgiseeq network driver 1.) warning with stack trace from include/linux/dma-mapping.h:516 (in dma_alloc_attrs()) called from drivers/net/ethernet/seeq/sgiseeq.c:742 (in sgiseeq_probe()) 2.) The exiting with "Sgiseeq: Page alloc failed, aborting.", -ENOMEM With the attached patch, the ethernet driver initializes, and works. Can mount NFS root filesystem, and already running for several hours (13+) building a kernel. Though, I don't know if it would interfere with other systems.

This sounds like something that really ought to go upstream. If you haven't already, I encourage you to join the linux-mips kernel mailing list here: http://vger.kernel.org/vger-lists.html#linux-mips And you can learn more about submitting patches to the Linux Kernel here: https://www.kernel.org/doc/html/latest/process/submitting-patches.html Although this is a MIPS-specific driver, it touches the networking subsystem, so you'll need to involve the Linux networking subsystem maintainers. They maintain a FAQ here: https://www.kernel.org/doc/html/latest/networking/netdev-FAQ.html An actual patch submission for this fix will need to go upstream via the netdev mailing list (which you don't have to join to actually submit to), with the linux-mips ML CC'ed.
But for that, first I will have to try it also on vanilla kernel, haven't I? Thanks for the directions anyway. Can you/someone try out the scenario/dirty patch of mine, to confirm that it not only works for me? Probably on a different machine which also uses the same net driver?
