I am getting repeated (10 a second or so) of this error message in my dmesg:
ivtv: IRQ: IVTV_IRQ_DEC_DMA_ERR ivtv: IRQ: IVTV_IRQ_DEC_DMA_ERR ivtv: IRQ: IVTV_IRQ_DEC_DMA_ERR I have tried multiple versions of the driver, from the "stable" old releases to the newest 0.3.4q. I have 2 PVR 250s. I just added the second one two days ago. I am unaware if the new one caused this as the recordings are still fine. The only thing that tipped me off to these messages was a 4.2 Gig /var/log/messages file!!! I do not have the second pvr 250 set up as I have directv and no second receiver to use yet. I do not know enough about driver options and the ivtv driver itself, as i have never passed it any options and it has worked fine. Now I am wondering what the cause of these messages is... If I start watching Live TV from a cold boot, I do not get these messages. When I start watching a recording, they start, and will not stop until another cold boot. I am baffled because the messages will start even if I'm watching something in MythVideo, which should be completely isolated.

Another thing to note is that the second tuner does not have radio, but ivtv seems to detect one. If anybody has any driver versions they think might work, or any suggestions/module options, etc. please let me know! Chris, if you want me to try specific stuff/code, just let me know! Whatever I can do to help you out, you'd really be just helping me out in the long run!!! With close inspection of my 4.2 Gig log file, these errors definitely started upon adding the second pvr 250... also, in the older driver version (marked stable...) I have no idea what to try, and I can't find any solutions searching gossimer threads or google at all... I have tried newer versions, like the recent thread spoke of where Chris was trying out new code, but that does nothing but change the 6 line error message to a 1 liner. I have also tried adding pci=routing, and/or noapic to my kernel options, I have changed PnP OS in BIOS to no/yes, disabled/enabled different IRQ settings, disabled APIC in BIOS, etc. I cannot get anything to work... The closest thing to error-free is disabling IRQ 11 in BIOS as a reserved IRQ, then the two PVR250s go on different IRQs and when recording, I do not get any error messages. Upon playback in MythTV, I start to get bombarded with the IRQ/DMA errors... I hope somebody can help me!!! -Mat P.S.
