Yes, which is also the case with 8250_fourport. 8250_fourport is just a probe module just like 8250_pnp or 8250_pci. > http://www.moschip.com/html/MCS9845.html That also clearly says its a PCI device. 8) What problem are we talking about here again? Sorry, I've completely lost track and this particular thread of 26 messages is soo convoluted and too much to re-read. Since you only appear to be the messenger, wouldn't it be far better to get the person with the problem to report and respond rather than sitting in the middle? -- Russell King Linux kernel 2.6 ARM Linux - http://www.arm.linux.org.uk/ maintainer of: 2.6 Serial core - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
