Wow, it didn't helped, I find out there is a difference between in-kernel and modules version of the driver. When compiled as modules (loaded/unloaded) suspending (and resuming) is working ok (enabled higmem and preempt back -- still no smp), when compiled in-kernel (see the config diff below), it doesn't resume. @@ -1263,8 +1263,8 @@ CONFIG_SND=y CONFIG_SND_TIMER=y CONFIG_SND_PCM=y -CONFIG_SND_HWDEP=m -CONFIG_SND_RAWMIDI=m +CONFIG_SND_HWDEP=y +CONFIG_SND_RAWMIDI=y CONFIG_SND_SEQUENCER=y # CONFIG_SND_SEQ_DUMMY is not set CONFIG_SND_OSSEMUL=y @@ -1282,8 +1282,8 @@ # # Generic devices # -CONFIG_SND_AC97_CODEC=m -CONFIG_SND_AC97_BUS=m +CONFIG_SND_AC97_CODEC=y +CONFIG_SND_AC97_BUS=y # CONFIG_SND_DUMMY is not set # CONFIG_SND_VIRMIDI is not set # CONFIG_SND_MTPAV is not set @@ -1347,7 +1347,7 @@ # CONFIG_SND_INDIGO is not set # CONFIG_SND_INDIGOIO is not set # CONFIG_SND_INDIGODJ is not set -CONFIG_SND_EMU10K1=m +CONFIG_SND_EMU10K1=y # CONFIG_SND_EMU10K1X is not set # CONFIG_SND_ENS1370 is not set # CONFIG_SND_ENS1371 is not set > As far as the first one is concerned, the genirq-* patches look suspicious.
