I've also got a siano card, but in my case it's embedded in my Dell laptop, so yanking it out and plugging it back in isn't even an option. The card is however a USB device and I've included the lsusb -v output at the end in case it's useful. I've tried the firmware you're referring too, but there's also a request for sms1xxx-nova-b-dvbt-01.fw in the dmesg and this is asked for first (in my case), with a siano supplied one sought if it can't find this first one. I'm not having problems with cold restarts, but suspend/hibernate sees the things go bad on resume. I've added some stuff to /etc/pm/sleep.d which unloads the modules and then reloads then on resume. It's a simple script: #!/bin/bash case $1 in hibernate) echo "Suspending to disk" modprobe -r smsdvb modprobe -r smsusb ;; suspend) echo "Suspending to RAM" modprobe -r smsdvb modprobe -r smsusb ;; thaw) echo "Suspend to disk is over, Resuming..." modprobe smsdvb modprobe smsusb ;; resume) echo "Suspend to RAM is over, Resuming..." modprobe smsdvb modprobe smsusb ;; *) echo "somebody is calling me totally wrong." ;; esac This addresses these problems for me. You might be able to add something similar to /etc/pm/power.d to unload modules to address the problem.
