I was looking to compare RT latency between this kernel and the latest from Ingo and I had the following warnings / errors building 2.6.10-mm1:
[no apparent compile / link errors] *** Warning: "snd_ac97_restore_iec958" [sound/pci/ac97/snd-ac97-codec.ko] undefined! *** Warning: "snd_ac97_restore_status" [sound/pci/ac97/snd-ac97-codec.ko] undefined! *** Warning: "del_mtd_partitions" [drivers/mtd/maps/scx200_docflash.ko] undefined! *** Warning: "add_mtd_partitions" [drivers/mtd/maps/scx200_docflash.ko] undefined! ... if [ -r System.map ]; then /sbin/depmod -ae -F System.map -b /var/tmp/kernel-2.6.10mm1-root -r 2.6.10-mm1; fi WARNING: /var/tmp/kernel-2.6.10 mm1-root/lib/modules/2.6.10-mm1/kernel/sound/pci/ac97/snd-ac97-codec.ko needs unknown sy mbol snd_ac97_restore_status WARNING: /var/tmp/kernel-2.6.10 mm1-root/lib/modules/2.6.10-mm1/kernel/sound/pci/ac97/snd-ac97-codec.ko needs unknown sy mbol snd_ac97_restore_iec958 WARNING: /var/tmp/kernel-2.6.10 mm1-root/lib/modules/2.6.10-mm1/kernel/drivers/mtd/maps/scx200_docflash.ko needs unknown symbol del_mtd_partitions WARNING: /var/tmp/kernel-2.6.10 mm1-root/lib/modules/2.6.10-mm1/kernel/drivers/mtd/maps/scx200_docflash.ko needs unknown symbol add_mtd_partitions ...
The following messages after rebooting...

and in dmesg, the following repeated a few times: snd_ac97_codec: Unknown symbol snd_ac97_restore_status snd_ac97_codec: Unknown symbol snd_ac97_restore_iec958 snd_ens1371: Unknown symbol snd_ac97_mixer snd_ens1371: Unknown symbol snd_ac97_bus
At this point, the system fails to work with my sound card. The .config is basically the same as used previously with 2.6.10-rc3-mm1-V0.7.33-04 (Ingo's realtime patches) without problems. [though I expected & saw plenty of unused symbols when I did make mrproper / xconfig for 2.6.10-mm1]
To fix this, should I just add the EXPORT_SYMBOL lines for these symbols snd_ac97_restore_status snd_ac97_restore_iec958 or is something more needed?
