Hi! I'm using a vanilla 2.6.10 linux kernel, patched with software suspend 2 (http://softwaresuspend.berlios.de/, patch: http://download.berlios.de/softwaresuspend/software-suspend-2.1.7-for-2.6.10.tar.bz2 ) I experienced DVB problems after suspending and resuming, even when I completely removed all DVB relevant modules before suspending. After resume, the card just wouldn't tune, everything else went fine. When before resuming there had been tuned a transponder and I did not interrupt the PC's power (reboot is ok), I could watch only channels from this transponder (quite funny, isn't it? I got behind this tricky effect watching the signal/noise values). I found out the problem was that the tuning thread wasn't launched, because the variables fe->thread_pid and fe->exit said there still was an appropriate thread, although it had been killed during unload of the modules. I checked initialization of those variables, which seemed to be the problem. With the following patch, everything now works fine. --- dvb-core/dvb_frontend.c.orig 2005-02-20 05:02:33.000000000 +0100 +++ dvb-core/dvb_frontend.c 2005-02-20 09:52:10.000000000 +0100 @@ -839,7 +839,11 @@ fe->events.overflow = 0; fe->dvb = dvb; fe->inversion = INVERSION_OFF; - + + /* here I put additional required initializatons */ + fe->thread_pid = 0; + fe->exit = 1; + printk ("DVB: registering frontend %i (%s)...\n", fe->dvb->num, fe->ops->info.name); I saw the cvs has already changed a lot since 2.6.10, but I believe this problem has not yet been touched. -------------- next part -------------- A non-text attachment was scrubbed...
