Using nvidia-kernel/nvidia-glx 1.0.8756 in combination with v4l2/bttv causes the tv tuner stop working and leads to system instability. It causes applications to randomly crash after a few minutes after starting or moving the xawtv window. It looks like it's caused by memory corruption. No error messages are being showed other than applications suddenly segfaulting/etc. Later on, random parts of the kernel die untill the system is rendered unusable. After downgrading to nvidia-kernel/nvidia-glx 1.0.8178-r3 everything works flawlessly again. I have tested this with both kernel 2.6.15 and 2.6.16 (gentoo-sources) with xorg-x11 6.8.2-r6. I have added the following lines in /etc/portage/package.mask as a workaround (and emerged nvidia-glx and nvidia-kernel again): -- >media-video/nvidia-kernel-1.0.8178-r3 >media-video/nvidia-glx-1.0.8178-r1 -- bttv output (might be tvcard specific): bttv: driver version 0.9.16 loaded bttv: using 8 buffers with 2080k (520 pages) each for capture bttv: Bt8xx card found (0). bttv0: Bt878 (rev 17) at 0000:00:0e.0, irq: 20, latency: 32, mmio: 0xef000000 bttv0: detected: Pinnacle PCTV [bswap] [card=39], PCI subsystem ID is bd11:1200 bttv0: using: Pinnacle PCTV Studio/Rave [card=39,autodetected] bttv0: gpio: en=00000000, out=00000000 in=00ff43df [init] bttv0: i2c: checking for MSP34xx @ 0x80... found bttv0: miro: id=16 tuner=1 radio=fmtuner stereo=yes bttv0: using tuner=1 bttv0: i2c: checking for MSP34xx @ 0x80... found
Please, test w/ recent x11-drivers/nvidia-drivers versions. Thanks.
(In reply to comment #1) > Please, test w/ recent x11-drivers/nvidia-drivers versions. Thanks. > I'm using Xorg 7.0.0 with Nvidia drivers 1.0-8762 and tvtime (with v4l2/bttv, kernel 2.6.17-gentoo-r4) now. This combination works very well.
