When I update to gentoo-sources 2.6.15 and then reboot. I get the following messages in my log: bad page state at free_hot_cold_page (in process 'artsd', page ffff810001db41f0) flags:0x4000000000000414 mapping:0000000000000000 mapcount:0 count:0 Backtrace: Call Trace:<ffffffff80158b81>{bad_page+113} <ffffffff80159382>{free_hot_cold_page+114} <ffffffff8016447d>{unmap_vmas+1293} <ffffffff80168c7d>{unmap_region+189} <ffffffff80169095>{do_munmap+565} <ffffffff80169938>{sys_munmap+72} <ffffffff8010eb26>{system_call+126} Trying to fix it up, but a reboot is needed On the forum somebody suggested unmasking of alsa-{driver|lib|header|utils}-1.0.11_rc2 solves the problem. Here is link to the forum page: http://forums.gentoo.org/viewtopic-t-419154-highlight-kernel.html After unmasking and rebooting the system everything is working fine.

Flameeyes, you should probably unmask latest alsa...
Anyone know which package is the culprit? i.e. is this alsa-driver users only, or is it an alsa-lib dealy which affects everyone? Arno, are you using alsa-driver or the in-kernel drivers?
I was already expecting something like this for 2.6.15, sigh I hoped it wasn't going to happen tho. I'll unmask it anyway, but I'd still like to have a few details on this.
I have problems with alsa-driver-1.0.11-rc2 on my x86 system. The build reports warnings for undefined symbols pm_register and pm_unregister and the next boot gives lots of unresolved symbol errors when loading the alsa modules. Here are the build warnings and those dmesg errors: *** Core build warning *** CC [M] /var/tmp/portage/alsa-driver-1.0.11_rc2/work/alsa-driver-1.0.11rc2/acore/misc_driver.o /var/tmp/portage/alsa-driver-1.0.11_rc2/work/alsa-driver-1.0.11rc2/acore/misc_driver.c: In function `register_pnp_pm_callback': /var/tmp/portage/alsa-driver-1.0.11_rc2/work/alsa-driver-1.0.11rc2/acore/misc_driver.c:687: warning: implicit declaration of function `pm_register' /var/tmp/portage/alsa-driver-1.0.11_rc2/work/alsa-driver-1.0.11rc2/acore/misc_driver.c:687: warning: assignment makes pointer from integer without a cast /var/tmp/portage/alsa-driver-1.0.11_rc2/work/alsa-driver-1.0.11rc2/acore/misc_driver.c: In function `unregister_pnp_pm_callback': /var/tmp/portage/alsa-driver-1.0.11_rc2/work/alsa-driver-1.0.11rc2/acore/misc_driver.c:706: warning: implicit declaration of function `pm_unregister' LD [M] /var/tmp/portage/alsa-driver-1.0.11_rc2/work/alsa-driver-1.0.11rc2/acore/snd.o *** Modules build warning *** Building modules, stage 2.

(In reply to comment #6) > You need to enable CONFIG_PM_LEGACY. Darn. You try to make your desktop system kernel lean by removing unnecessary power management baggage and it breaks the sound system build - sigh! Another concession to the world of laptops/notebooks I suppose. Thanks for the, extremely, speedy response.
(In reply to comment #6) > You need to enable CONFIG_PM_LEGACY. I have CONFIG_PM_LEGACY=y on my ~x86 system, I do not see the errors at boot, but do see the 'free_hot_cold_page' error with ALSA 1.0.10 (using alsa-driver not the kernel built in)
I'm using alsa-driver not the in-kernel drivers.
I have these problems too. After a warning form the ebuild I changed from using in-kernel drivers to alsa-driver but for the worse... I've tried numerous things to repair my system including make clean, removing all alsa packages, removing and re-emerging gentoo-sources. Now even alsasound won't start anymore. What is going on?
Graham, Arno, could you please try the in-kernel drivers to confirm that the problem is only with the alsa-driver version? Before unmerging alsa-driver, take a look at the output of "equery files alsa-driver" - note the locations of the files under /lib/modules. Next unmerge alsa-driver, and then manually delete the files from /lib/modules (these are not removed by portage, this might explain Andr

Created attachment 76856 [details] script to remove files left after emerge unmerge alsa-driver
Daniel: It seems like your advice was correct. It took some time, I first had to install alsa-driver before I could follow it and some strange things happened afterwards. For example I still have alsactl complaining at boot time, but at least I have sound again. I used the equery output to write a very simple script, see attachment.
OK everything back to normal now. Maybe some extra information could be supplied to users: 1. "how to move back and forth between in-kernel and out-of-kernel drivers" 2. background information (explaining briefly what happens) The first should imho probably be included in the Gentoo ALSA guide.
(In reply to comment #3) > Anyone know which package is the culprit? i.e. is this alsa-driver users only, > or is it an alsa-lib dealy which affects everyone? This problem is due to changes in kernel API (the API is changing too often in the last releases). There is a two-line patch to solve this problem: http://lkml.org/lkml/2005/12/9/124. It worked for me. The in-kernel driver has this patch applied.
In reply to comment #11: I can confirm that the in-kernel drivers are working fine. I have no problem at all. So alsa-driver has to be the culprite. And the little guide in comment #11 worked fine to getting rid of the alsa-drivers modules in /lib/modules/2.6.15-gentoo/.
Fixed in alsa-driver-1.0.10-r2
