Hi,
As part of recent testing I attempted to build current 1.0.24 alsa-driver on an older machine with 2.4.21-99 kernel .
'configure' and 'make' proceeded uneventfully, but 'rcalsasound start' gave following error:-
"Starting sound driver: snd-ice1712 /lib/modules/2.4.21-99-athlon/kernel/ sound/acore/snd.o: unresolved symbol lock_kernel /lib/modules/2.4.21-99-athlon/kernel/sound/acore/snd.o: unresolved symbol unlock_kernel /lib/modules/2.4.21-99-athlon/kernel/sound/acore/snd.o: insmod /lib/ modules/2.4.21-99-athlon/kernel/sound/acore/snd.o failed /lib/modules/2.4.21-99-athlon/kernel/sound/acore/snd.o: insmod snd-ice1712 failed"
This does not occur on 1.0.23 (or previous builds that I have tested).
I am aware that there was discussion about ditching 2.2/2.4 support, but my understanding was that 1.0.24 should build and work, but may be the last to do so - is that correct?
Well, I don't think any developers actually tested 2.2/2.4 with the real machine. We usually test the builds, but no more than that. So it's not unsurprising if 1.0.24 doesn't work with 2.4 kernel.
Is there a simple fix for this problem?
Stick with 1.0.23 :) There are no big changes regarding ice1712 driver since 1.0.23. The only change is the support of delta66e.
Or, just adding #include <linux/smp_lock.h> in include/adriver.h might fix the problem.
