2.6.14-rc4: dma_timer_expiry [was 2.6.13-rc2 hangs at boot]

I just tested 2.6.13-rc4. At boot it prints:
"dma_timer_expiry: dma status == 0x61" many times.
That's the same problem as in 2.6.13-rc2.

If I apply the following patch, everything seems to be fine.
I'm not sure if this is the right thing to do, but it works for me.
