I've been trying to get xen working, using sys-kernel/xen-sources-2.6.16.28-r2 from portage. My kernel boots, but fails to bring up the network card. The card works perfectly with sys-kernel/gentoo-sources-2.6.18-r6. When I check dmesg I find the following error: b44.c:v0.97 (Nov 30, 2005) ACPI: PCI Interrupt 0000:02:01.0[A] -> GSI 17 (level, low) -> IRQ 17 b44: No usable DMA configuration, aborting. b44: probe of 0000:02:01.0 failed with error -5 Reproducible: Always Actual Results: The network card doesn't work. Expected Results: The network card to work. I have tried multiple kernel builds with no success...
Created attachment 108478 [details] dmesg from the Xen kernel
ok, the card seems to work fine with xen-sources-2.6.16.42 from the marineam-xen overlay.
xen-sources-2.6.16.28 is long gone, newer kernels should be fine. Closing
