No oopses or kernel crashes with this version of the driver (0.8.46) this was a problem with previous versions (I have machines running a customized 0.8.33 version that need to be rebooted daily otherwise they will crash in a number of different ways). This problem only happens when I capture cc along with the video. My gut tells me that it is probably not heat related because the problem can occur with in a few seconds after starting the capture processes. I also get similar SCERRs when I kill the capture processes. I would be glad to help find this bug if you give me some pointers on where to look, I have a test machine available. modules.conf NOTE: I have tried increasing the vbibufs to 32 and that had no noticable effect. pre-install bttv modprobe -k msp3400; modprobe -k tuner; modprobe -k btaudio options i2c-core i2c_debug=0 options i2c-algo-bit bit_test=1 i2c_debug=0 options bttv irq_debug=0 fdsr=0 tuner=17 sloppy=1 chroma_agc=1 mmap=1 vbibufs=16 radio=0 v4l2=1 gbuffers=32 bttv_verbose=0 automute=1 options msp3400 simple=0 debug=0 options tuner type=17 options btaudio digital=1 analog=0 debug=0 bttv messages from capture start until first EIO message received.

test03 kernel: bttv1: SCERR @ 064fa000,bits: HSYNC SCERR* -----Original Message----- From: video4linux-list-admin@xxxxxxxxxx [mailto:video4linux-list-admin@xxxxxxxxxx]On Behalf Of Cory Powers Sent: Monday, November 04, 2002 5:56 PM To: video4linux-list@xxxxxxxxxx Subject: bttv Input Output Errors I am using bttv 0.8.46 on kernel 2.4.19 with the v4l2 and ac4 patches and 5 ATI TV Wonder cards. I am capturing mpeg 1 video at 1fps 50kbps bitrate with an audio stream at 32kbs with a custom version of mp1e. I am also trying to capture the closed caption text at the same time using the v4l2 streaming interface. After less than 20 minutes of capture I get Input/Output (5) errors when trying to dequeue a buffer, this error happens at the same time on both the cc and mp1e capture programs. I also receive a lot of SCERRs in the log file just prior to the Input/Output errors. Has anyone seen this behavior before? Does anyone know what may cause these errors (the video signal is perfect)? Are there any parameters that I can tweak to help this condition? Thanks, Cory
