Hi all again, I would like just to re-state the issue and try to rationalize a possible debugging strategy. So my questions would be: 1) Is there any possibility, with a Fedora kernel, to activate some run-time debugging/verbosity option for the USB/ehci/usb-storage subsystem in order to try to see where the problem is? 2) About compiling the kernel and git bisect: a) As mentioned, this is a Fedora system, I'm not sure how many, if any, changes they did. Should I follow the Fedora wiki instruction on how recompile a kernel or should I simply use one from kernel.org? b) While I do not like it, I'm ready to give it a try if really, really necessary. Where do I find the instruction of how to proceed, specifically (again) for a Fedora system? Thanks a lot in advance, bye, -- piergiorgio -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
