Comment 47 for bug 211644

I just checked the modules in my /lib/modules to make sure that there is only one of the snd-hda-intel.ko file in each set of modules. Here's the output of the find command that I ran:

xxx@xxxxx:/lib/modules$ find . -name 'snd-hda-intel.ko'
./2.6.20-16-generic/kernel/sound/pci/hda/snd-hda-intel.ko
./2.6.20-16-generic/extra/snd-hda-intel.ko
./2.6.22-14-generic/ubuntu/media/snd-hda-intel/snd-hda-intel.ko
./2.6.24-16-generic/ubuntu/sound/alsa-driver/pci/hda/snd-hda-intel.ko
./2.6.24-16-rt/ubuntu/sound/alsa-driver/pci/hda/snd-hda-intel.ko

I again looked through the patches to the 2.6.24 kernel (package revision 16.30) looking for a patch to the sigmatel file.

xxx@xxxxx:~/projects/linux/linux-2.6.24/debian$ rgrep -l sigmatel *
binary-custom.d/lpia/patchset/0010-hda_sigmatel.patch
changelog.historical

The 0010 file doesn't have anything resembling the fix to the sigmatel_patch.c file. It makes no sense to me why the realtime kernel (at package revision 16.30) works and the generic kernel (also at package revision 16.30) does not. Are there any changes between the two kernels that could cause this issue to magically be fixed in the rt kernel?

Thanks,
wt
