Francois Romieu wrote: Default to disabling PCI DAC as this option appears unsafe on amd64 (original suggestion by Hans-Frieder Vogt <hfvogt@xxxxxxxx>). The driver will typically report PCI System error when something goes wrong. The relevant interrupt is not masked any more and the driver can thus be disabled.
Can this interrupt be used at runtime to detect that DAC isn't working?
