If your kernel is tainted (by having a binary-only module loaded), then you cannot get valid data. > Jul 16 18:49:04 mango kernel: ALSA sound/core/pcm_lib.c:169: XRUN: pcmC0D0c > Jul 16 18:49:04 mango kernel: [<f08c0357>] snd_pcm_period_elapsed+0x2e7/0x460 [snd_pcm] > Jul 16 18:49:04 mango kernel: [<f08edb8e>] snd_cs46xx_interrupt+0x1be/0x1f0 [snd_cs46xx] > Jul 16 18:49:04 mango kernel: [<c0105737>] handle_signal+0xb7/0x120 > Jul 16 18:49:04 mango kernel: [<c01073fa>] handle_IRQ_event+0x3a/0x70 > Jul 16 18:49:04 mango kernel: [<c0107761>] do_IRQ+0x91/0x130 > Jul 16 18:49:04 mango kernel: [<c0105be4>] common_interrupt+0x18/0x20 > Jul 16 18:49:04 mango kernel: [<c011a2f0>] __do_softirq+0x30/0x80 > Jul 16 18:49:04 mango kernel: [<c011a366>] do_softirq+0x26/0x30 > Jul 16 18:49:04 mango kernel: [<c01077cd>] do_IRQ+0xfd/0x130 > Jul 16 18:49:04 mango kernel: [<c0105be4>] common_interrupt+0x18/0x20 > Jul 16 18:49:04 mango kernel: ALSA sound/core/pcm_lib.c:169: XRUN: pcmC0D0p > Jul 16 18:49:04 mango kernel: [<f08c0357>] snd_pcm_period_elapsed+0x2e7/0x460 [snd_pcm] > Jul 16 18:49:04 mango kernel: [<c011e1c6>] update_process_times+0x46/0x60 > Jul 16 18:49:04 mango kernel: [<f08edb8e>] snd_cs46xx_interrupt+0x1be/0x1f0 [snd_cs46xx] > Jul 16 18:49:04 mango kernel: [<c011e4bf>] do_timer+0xdf/0xf0 > Jul 16 18:49:04 mango kernel: [<c010b378>] timer_interrupt+0xb8/0x140 > Jul 16 18:49:04 mango kernel: [<c01073fa>] handle_IRQ_event+0x3a/0x70 > Jul 16 18:49:04 mango kernel: [<c0107761>] do_IRQ+0x91/0x130 > Jul 16 18:49:04 mango kernel: [<c0105be4>] common_interrupt+0x18/0x20 > Jul 16 18:49:04 mango kernel: [<c011a2f0>] __do_softirq+0x30/0x80 > Jul 16 18:49:04 mango kernel: [<c011a366>] do_softirq+0x26/0x30 > Jul 16 18:49:04 mango kernel: [<c01077cd>] do_IRQ+0xfd/0x130 > Jul 16 18:49:04 mango kernel: [<c0105be4>] common_interrupt+0x18/0x20 Takashi Iwai mentioned there were some patches available to daemonize softirq processing, and that these might help.
