"pnp o/s = no" causes the bios : to assign an irq to the pcic controller, meaning the pcic controller : raises that interrupt on insertions/removals, but the driver, : operating in polling mode, never clears the interrupt so the machine : wedges trying to service it? if this is correct, how does ddb : manage to unwedge things? I'm not sure. I suspect that it is assigning other interrupts differently. I'm not entirely sure. : the fix in -current is the pci interrupt routing code which allows : us to set "pnp os = yes" in the bios and let freebsd make irq : assignments only for devices it understands? FreeBSD -current doesn't support this just yet. : any chance this will MFC-ed? To be honest, the odds are low. It won't be soon because the code isn't ready for prime time just yet. We've still hit problem cases from time to time. Warner To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
