My laptop does not have regular DB-9 serial connectors, only USB. So I ordered a USB to serial converter, configured a 2.6.0-test3 kernel, added a console=/dev/ttyUSB0 to the kernel command line and connected this to my desktop with a null modem adapter. However, I am unable to get output from this setup on the desktop. On another setup I can get a normal serial console output, so I am fairly confident I can set things up correctly. Googling around and doing a search on lkml archives gave some minimal help, but I can find very little info past early to mid 2.5 kernels. The configuration doesn't quite seem to work the way I read documentation. For instance, the web pages I can find indicate I should be able to build this modular; however the configuration makes the setting of console on usb depend on USB being y and EXPERIMENTAL being defined. In /var/log/messages I can see the USB-to-serial converter being recogized and the driver being loaded, just before the synaptics touchpad is probed. It looks like things are correct, but, as I said, I am unable to get output. Am I headed for frustration, or is there some advice to get good results? Is there any advice I might be able to use to get this going? I really want to be able to catch some oops output. - 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/
