While I was booting Linux, I saw a 'transparent bridge' from dmesg and started digging up because I was fighting against 'interrupt storming' and 'stray IRQ' problems with the latest Intel chipsets recently and I had a feeling that it's somehow related. http://lxr.linux.no/source/drivers/pci/probe.c?v=2.6.8.1#L195 http://lxr.linux.no/source/arch/i386/pci/fixup.c?v=2.6.8.1#L192 http://lxr.linux.no/source/arch/i386/pci/irq.c?v=2.6.8.1#L870 http://lxr.linux.no/source/arch/i386/pci/irq.c?v=2.6.8.1#L1017 But I don't see any special treatment in FreeBSD's PCI driver. 1. Is this relevant for FreeBSD? 2. Is this related to the problems (esp. SMP)? Thanks, Jung-uk Kim
