Hi all,
let me first note I am an absolute beginner with VDR. I'm running a home server since serveral years, curently with Ubuntu 10.04LTS. Few weeks ago I've installed yaVDR and a DVB-T stick, without any problems. So I went on and added a pvr150 using pvrinput. The card itself works, I'm able to schedule recordings, stream TV aso. The server itself usually sleeps (suspend to ram). A sheevaplug wakes the server (wake on lan) whenever something interesting happens (like the next recording is ready to start). So here starts my problem: whenever the server wakes up to start a recording using the pvr150, it crashes after a short time:
Jul 3 11:01:35 ghost kernel: [11592.705028] vdr[9472]: segfault at 7f93c2ca7386 ip 00007f93c7223de7 sp 00007f93ae7f3520 error 4 in libgcc_s.so.1[7f93c7214000+16000]
After the crash the server is unable to suspend:

For the suspend thing I've followed Tobis advice: http://www.e-tobi.net/blog/201…vdr-teil-9-suspend-to-ram (German page). I assume (just a beginners wild guess) there is something wrong with this module loading/unloading stuff on suspend and wake-up. Do you have any hints? Something special for the pvr150?

PS: did I forgot any important information?
