It's not that initialisation fails (I'm booting the kdump kernel with pci=nomsi, however, I also tried without). The problem is that the kernel gets interrupts from this device where it was not configured. SAPIC interrupts are disabled before shutdown, but not MSI interrupts. However, that patch addresses only the issue to disable interrupts before the cciss driver re-enables the interrupts again. When that happens, there could still be a problem because the device is in an invalid state. The firmware vendor seems to work on a fix to support the reset message. So I think we can ignore this issue here for now. > Disabling MSI blindly after a crash is a problem in terms of > reliability as we are traversing all pci_dev structures. (As you already > mentioned.) Yes. :( Regards, Bernhard
