I've tried to configure my system for suspends and here are my conclusions, maybe it will be helpful:
Make sure no applications are using drivers that generally make problems after suspend, that means you have to stop/kill them before suspending. I use pm-utils script to stop application before suspend and start applications after that.
Make sure you reload the drivers after resume. pm-utils has a feature to unload modules before suspend and reload them after resume automatically, check the SUSPEND_MODULES configuration. That method works fine for my DVB-S drivers, but don't work for my WiFi card, so I had to reload the driver after resume in my script.
Hope it helps.

don't know on what driver you report it, but since I know you also have
saa7134 driver devices, nobody claimed so far that dvb is suspend/resume
safe.
I recently reported that people have to stay aware after resume, that
even without using any dvb app actually during suspend, analog needs to
be re-initialized first after that to get the tda10046 in a proper state
for DVB-T again, at least on hybrid devices. Unshared DVB-S tuners and
demods do stand this already. (medion 8800quad, CTX948, Asus 3in1)
You can suspend to RAM on analog for example with a running tvtime and
resume, but dma sound on saa7134-alsa is also not handled yet. Analog
sound works.
That is the status as far I have it.
Cheers,
Hermann
