The following message is returned when trying to compile a 2.6.4 kernel on amd64: WARNING: /lib/modules/2.6.4-gentoo/kernel/sound/core/snd.ko needs unknown symbol memcpy_fromio WARNING: /lib/modules/2.6.4-gentoo/kernel/sound/core/snd.ko needs unknown symbol memcpy_toio Naturally, alsa cannot be loaded or run with this kernel, either.... Reproducible: Always Steps to Reproduce: 1. Configure ALSA sound support. 2. Compile the kernel. 3. Reboot the system with this kernel and watch it fail... Actual Results: Sound did not function. Expected Results: Built up a correct "versions" table containing the missing memcpy_* symbols.
This is a kernel bug (it breaks alsa) and is fixed with the new ebuild. I had the same problem myself. Try the 2.6.5-rcX kernel series, it's also fixed in that. Tamran
It was a kernel toolchain bug and it appears to be fixed in the latest gentoo-dev-sources 2.6.4-r1 ebuild. I've also received info. that it is fixed in the latest 2.6.5 kernel series.
