provide more info to debug. > Regards, Mark One thing you could try is to modprobe the driver and then from another terminal, do a `ps aux' and see if the modprobe is in "R", "D" or "S" state. Then do an echo t > /proc/sysrq-trigger (or "echo w" if it was in D state) and then run "dmesg -s 1000000 > foo", then send us the backtrace for that stuck modprobe instance. Please ensure that your email client doesn't wordwrap the trace!
