Comment(by dsd):

 Here's the trace:

 {{{
 SND_PCM_IOCTL_HWSYNC
 snd_pcm_update_hw_ptr()
 snd_pcm_update_hw_ptr_pos()
 snd_cs5535audio_pcm_pointer()
 cs5535audio_playback_read_dma_pntr()
 cs_readl(cs5535au, ACC_BM0_PNTR)
 <hang>
 }}}

 It hangs on inb(0x14e0). The port address is correct, I confirmed it on a
 machine that doesn't hang. Veery strange. Will save-nand and try 2273 now.
