I was in doubt, how your equation 60 x HZ / 100 could even produce 600 ms.... But I supposed some recalculation elsewhere... > You probably got this message by setting IVTV_SDRAM_SLEEPTIME to 600, > right? At HZ=250 that comes to 2.4 seconds. Yup.

I tried, it looks, the initialization failure is less frequent than with the original setting, but (as you can see in the attached log) it is many times still present. Formerly it was let's say 50:50, now ~75% success. I tried also parameters ivtv_pci_latency and newi2c : they have no influence on the process, the ratio success/failure seems to be the same. > > But another possible reason might be an underpowered powersupply. I do not think so: a)my PSU is Chieftec 460W, which should be able to manage single core Athlon64-3200+ without problems, esp. because I have not too power hungry videocard (Matrox G450, AGP, just passive cooler is on the chip => it cannot consume to much power). And the system is NOT overclocked. b)When my system is warmed up, X running, PVR-350 is producing mpeg2 stream, which I am recording on disks (I am using raid1 array with reiserfs) and simultaneously watching it with xine, then power consumption should be much higher than during simple initialization of PVR-350 by loading of the modules from text console, right? And I did not ever noted any strange failures/lock-ups etc. at such moment, only during manipulations with loading/unloading of ivtv driver. c)If PSU was involved, why the situation would be ivtv_driver-version dependent? Just to exclude other factors: I ran memtest86 for almost week in the past, when I built the system: without any single error.
Thank you, Hans, for fast reply... -- Jan Taimr --------------------------------------- The worst computer virus is an end-user ---------------------------------------
