Unfortunately, I can confirm this: gcc-4.1 _breaks_ ivtv-0.6. At least the gcc that ships with SuSE 4.1 (rpm: gcc-4.1.0-25), I've not tested vanilla gcc 4.1. However, please note that I did not have any problem with SuSE gcc 4.1 yet but with the ivtv 0.6 driver. VMware Server Beta, for instance, runs fine under vanilla 2.6.16.22, both compiled with SuSE's gcc 4.1. Therefore I'd suspect that some bug in ivtv is triggerd by gcc 4.1. Or, more unlikely but still possible, ivtv shows a bug in gcc 4.1. Can somebody confirm this? To verify the compiler issue, I've built vanilla gcc-3.4.6 under SuSE 10.1 (using gcc 4.1 ;-) and used gcc 3.4.6 to compile kernel 2.6.16.22 and ivtv-0.6.3. Now, loading the ivtv module succeeds: dmesg: Linux version 2.6.16.22 ([EMAIL PROTECTED]) (gcc version 3.4.6) #2 Thu Jun 29 20:17:14 CEST 2006 ivtv: ==================== START INIT IVTV ==================== ivtv: version 0.6.3 (tagged release) loading ivtv: Linux version: 2.6.16.22 K7 REGPARM 4KSTACKS gcc-3.4 ivtv: In case of problems please include the debug info between ivtv: the START INIT IVTV and END INIT IVTV lines, along with ivtv: any module options, when mailing the ivtv-users mailinglist. ivtv0: Autodetected Hauppauge WinTV PVR-350 card (cx23415 based) ivtv0: Unreasonably low latency timer, setting to 64 (was 32) msp3400 1-0040: MSP4418G-A2 found @ 0x80 (ivtv i2c driver #0) msp3400 1-0040: MSP4418G-A2 supports nicam and radio, mode is autodetect and autoselect tuner 1-0061: chip found @ 0xc2 (ivtv i2c driver #0) tveeprom 1-0050: Hauppauge model 48134, rev J321, serial# 2771457 tveeprom 1-0050: tuner model is Philips FM1216 (idx 21, type 5) tveeprom 1-0050: TV standards PAL(B/G) (eeprom 0x04) tveeprom 1-0050: audio processor is MSP4418 (idx 25) tveeprom 1-0050: decoder processor is SAA7115 (idx 19) tveeprom 1-0050: has radio, has IR remote saa7115 1-0021: saa7115 found @ 0x42 (ivtv i2c driver #0) ieee1394: Host added: ID:BUS[0-01:1023] GUID[00e0180000c40766] saa7127 1-0044: saa7127 found @ 0x88 (ivtv i2c driver #0) ivtv0: loaded v4l-cx2341x-enc.fw firmware (262144 bytes) ivtv0: loaded v4l-cx2341x-dec.fw firmware (262144 bytes) ivtv0: Encoder revision: 0x02050032 ivtv0: Decoder revision: 0x02020023 ivtv0: Allocate DMA encoder MPEG stream: 128 x 32768 buffers (4096KB total) ivtv0: Allocate DMA encoder YUV stream: 161 x 12960 buffers (2048KB total) ivtv0: Allocate DMA encoder VBI stream: 80 x 26208 buffers (2048KB total) ivtv0: Allocate DMA encoder PCM audio stream: 455 x 4608 buffers (2048KB total) ivtv0: Create encoder radio stream ivtv0: Allocate DMA decoder MPEG stream: 16 x 65536 buffers (1024KB total) ivtv0: Allocate DMA decoder VBI stream: 512 x 2048 buffers (1024KB total) ivtv0: Create decoder VOUT stream ivtv0: Allocate DMA decoder YUV stream: 20 x 51840 buffers (1024KB total) ivtv0: loaded v4l-cx2341x-init.mpg firmware (155648 bytes) tuner 1-0061: type set to 5 (Philips PAL_BG (FI1216 and compatibles)) ivtv0: Initialized Hauppauge WinTV PVR-350, card #0 ivtv: ==================== END INIT IVTV ==================== Of course, capturing and everything else is fine too now.
