I now compiled my own kernel (2.4.27) without versioned symbols and without included sound modules. Compiling worked now just fine, some warnings about some unused vars, only. However, this means that debian package kernel-headers-2.4.27 for is totally broken for sparc32. I'll investigate this further and file a bug report about this (probably marked critical as this really sucks :-( ). However, there is another problem with alsa: it wants some PCI stuff but my machine in SBUS-only: cp snd-sun-amd7930.o snd-sun-dbri.o /lib/modules/2.4.27/kernel/sound/sparc make[1]: Verlasse Verzeichnis »/usr/src/alsa-driver-1.0.7/sparc« /sbin/depmod -a 2.4.27 -F /lib/modules/2.4.27/build/System.map depmod: *** Unresolved symbols in /lib/modules/2.4.27/kernel/sound/acore/snd-page-alloc.o [...] dtkstation:/usr/src/alsa-driver-1.0.7# modprobe snd-sun-dbri /lib/modules/2.4.27/kernel/sound/acore/snd-page-alloc.o: /lib/modules/2.4.27/kernel/sound/acore/snd-page-alloc.o: unresolved symbol pci_free_consistent /lib/modules/2.4.27/kernel/sound/acore/snd-page-alloc.o: /lib/modules/2.4.27/kernel/sound/acore/snd-page-alloc.o: unresolved symbol pci_alloc_consistent /lib/modules/2.4.27/kernel/sound/acore/snd-page-alloc.o: insmod /lib/modules/2.4.27/kernel/sound/acore/snd-page-alloc.o failed /lib/modules/2.4.27/kernel/sound/acore/snd-page-alloc.o: insmod snd-sun-dbri failed I doubt that pci_alloc_* function will ever be in my kernel or any module that comes with it. So: alsa broken on non-PCI sparc systems?
