never mind, i just emerge --sync'd and saw in the changelog that it already got adressed... somehow :) i hope the modules get loaded anyway with the new changes? but i guess i will see... thx, *** This bug has been marked as a duplicate of bug 253535 *** |
With newest kernel the module snd_hda_intel isn't listed in the used-by snd_hda_codec_analog lsmod row and therefore the initscript hangs with rmmod --wait at snd_hda_codec_analog. this is a general issue with dynamic module dependancies not listed with ''lsmod''. correct solution is to 1. don't unload modules at shutdown-time 2. do a while loop unloading the snd_ modules with refcount 0 until there are no more unused snd_ modules left. (this removes all modules) Reproducible: Always Steps to Reproduce: 1. /etc/alsasound stop with snd_hda_intel module and snd_hda_codec_analog loaded (kernel 2.6.29-rc1+) Actual Results: the script hangs at "rmmod --wait snd_hda_codec_analog" this is especially fatal, as the modules are unloaded at shutdown-time and so the laptop doesn't shutdown anymore... Expected Results: unloading using the static module dependancies is broken, instead begin with unloading unused modules suse initscript does this (it works): mod=$(grep -m1 -E '^(snd[^ ]*|ac97_bus) [0-9]+ 0' /proc/modules) while [ -n "$mod" ]; do mod=${mod%% *} /sbin/modprobe -r $mod mod=$(grep -m1 -E '^(snd[^ ]*|ac97_bus) [0-9]+ 0' /proc/modules) done
