With a kernel built from sources cvsupped today, I get he following messages when booting: ... pcib0: on motherboard pci0: on pcib0 atapci0: port 0 x3f4-0x3f7,0x1f0-0x1f7 at device 1.0 on pci0 atapci0: Busmastering DMA not supported panic: resource_list_alloc: resource entry is busy I had problems with this old system and the ata drivers before. The EIDE hardware apparently reported its IRQ as 0, which normally is reserved for the timer interrupt. Until recently, the ata driver contained code to force the IRQ back to 14 or 15 when it encountered such hardware. I do not see that code in the newest driver. Indeed, when I revert to the ata driver of last Sunday, the system boots and runs perfectly again. Is anybody having the same problem ? Any idea for a solution ?
