It never happened after applying this patch (not the right circumstances
I think). It always printed this:

intel8x0: ignored irq, status = 0x300100, sta_mask = 0xf0

And sound worked.

Today discovered this message from dmesg:

intel8x0: ignored irq, status = 0x300100, sta_mask = 0xf0
intel8x0: ignored irq, status = 0x300100, sta_mask = 0xf0
intel8x0: ignored irq, status = 0x300100, sta_mask = 0xf0
irq 7: nobody cared!

And mplayer stalls again. The 'ignored irq' message was the same and no
additional messages
after call trace.
