* [linux-dvb] mt352 no more working after suspend to disk @ 2009-02-09 11:33 Nico Sabbi 2009-02-09 22:16 ` hermann pitton 0 siblings, 1 reply; 6+ messages in thread From: Nico Sabbi @ 2009-02-09 11:33 UTC (permalink / raw) To: linux-dvb Hi, if I suspend to disk and next resume I have to manually remove and reload my mt352 driver, otherwise it complains of a lot of i2c errors. My kernel is suse's 2.6.27. Is this problem fixed in recent kernels or in hg?

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 ^ permalink raw reply [flat|nested] 6+ messages in thread

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.

Fine so far then without a running DVB-S app. That we don't get trouble with those maybe building high end linux media machines currently, status for me for the other reception methods is as announced above :) Cheers, Hermann ^ permalink raw reply [flat|nested] 6+ messages in thread
