Hi Gilles and Jan, what is wrong with PCI_MSI? In late june there was a discussion on this list about irq-sharing [1]. Jan's statement at the end of the discussion: > The better news is that modern hardware now more and more provides MSI, > and that's an inherently unshared IRQ source. We consider ordering custom built pcie boards (msi) to solve the irq-sharing problem i have with my pci board. Bad idea ?
