That's a bug in sound/pci/cs4281.c.
There's a debug patch in -mm ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.17-rc5/2.6.17-rc5-mm3/broken-out/debug-shared-irqs.patch which trips up drivers which request an IRQ before their IRQ handler is ready to accept IRQs (they'll crash in real life if the IRQ is shared).

That looks like the same thing?

So does that.

Try reverting debug-shared-irqs.patch, or disable the sound driver? - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
