This patch disable interrupts on all ports during initialization. The current assumes that the firmware has already disabled all interrupts on all ports. We have encountered some boards that do not always disable interrupts (XES XPedite 6200 for instance) on a soft reset. This patch prevents a kernel panic if a packet is received before the DMA ring buffers are setup for a port on which interrupts are left enabled by the firmware.
You probably have bigger problems than the interrupt being left enabled. If the interrupt is left enabled, the DMA engine is probably left enabled, and if a packet happens to come in before the driver can properly configure them, some random part of memory will get overwritten. The firmware needs to disable this device before transferring control to the kernel, both the interrupts and the DMA, there is no way to fix this in the kernel. - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
