As suggested on the linux.usb mailing list, I've added some additional debug print statements to the first bad kernel. They are not triggered by "lsusb -v" though. I'm attaching kernel debug output from the boot sequence of two kernels: - the bad one, with additional print statements - the last good one, without additional print statements The difference in the startup behavior is remarkable.
