I recompiled 2.6.21-rc6-mm1 from fresh sources. It still hangs initializing USBm but this time your patch applied.
I rebooted with your patch, and got: Detailed lists of all the USB devices found (printer,mouse,...) Then usbcore registered various drivers, such as usblp, usb-storage, libusual, usbserial, ipaq These messages were intermixed with messages from the md raid system initializing The three last lines were: sdhci: Secure digital host controller interface driver sdhci: copyright Pierre Ossman usbcore: registered new interface driver hiddev And then the machine hung completely. I'll have a look at bisecting. :-( - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
