(Re: interrupts not being seen by es18xx) That is indeed what it soundeed like, or the first bit at least.
What does cat /proc/config.gz | grep CONFIG_ALPHA_ say? Miuchael, and for you? For some Alpha configs, arch/alpha/kernel/es1888.c is compiled and for some not. I expect for you (Bob) it's compiled in? And Michael?
Here is the requested list of CONFIG_ALPHA_* items for the 2.6.25-rc4+iommu_patch kernel with support for snd-es18xx and snd-sb8:
CONFIG_ALPHA=y CONFIG_ALPHA_MIATA=y CONFIG_ALPHA_EV5=y CONFIG_ALPHA_CIA=y CONFIG_ALPHA_EV56=y CONFIG_ALPHA_PYXIS=y CONFIG_ALPHA_SRM=y CONFIG_ALPHA_LEGACY_START_ADDRESS=y
_From arch/alpha/kernel/Makefile, obj-${CONFIG_ALPHA_MIATA} adds es1888.o as a built-in object, so yes, it's built-in.
I never noticed the init support for the ES1888 chip before... The code appears to set up DMA channel 1, but does not mention anything about the second 16-bit DMA channel.
