My DVB card works like a charm on 2.6.27-rc4 (full .config : http://omploader.org/veGd1) but doesn't work any more on newer kernels. When i try to use my DVB card on 2.6.27.6, i get these errors in dmesg : divide error: 0000 [1] PREEMPT CPU 0 Modules linked in: nouveau drm w83627hf hwmon_vid sky2 forcedeth i2c_nforce2 k8temp Pid: 2678, comm: kdvb-fe-0 Not tainted 2.6.27.6 #1 RIP: 0010:[] [] simple_dvb_calc_regs+0x9c/0x227 RSP: 0018:ffff880076a35d30 EFLAGS: 00010246 RAX: 00000000217f7080 RBX: ffff880076a35db0 RCX: 0000000000000000 RDX: 0000000000000000 RSI: ffffffff807e1a00 RDI: ffff88007fbc8810 RBP: ffff880076a35da0 R08: ffff880076a35d76 R09: 0000000000000000 R10: 00007fffb8cd9ff8 R11: 0000000000000202 R12: ffff88007f16bba0 R13: ffff88007f16bba0 R14: ffff88007fbc8c08 R15: ffff88007fbc8810 FS: 00007f66af02a750(0000) GS:ffffffff80815e80(0000) knlGS:0000000000000000 CS: 0010 DS: 0018 ES: 0018 CR0: 000000008005003b CR2: 00007f66ae30aeb5 CR3: 000000006fa1f000 CR4: 00000000000006e0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000ffff0ff0 DR7: 0000000000000400 Process kdvb-fe-0 (pid: 2678, threadinfo ffff880076a34000, task ffff880066081630) Stack: ffffffff8088e9d8 ffff8800768e9678 ffff880076a35d70 ffffffff8022513d 0000000000000001 ffff8800768e9668 ffffffff807e0b80 00000013fe9c93db 8e01880000002320 ffff88007fbc8810 ffff88007f16bba0 0000000000000000 Call Trace: [] ? __dequeue_entity+0x61/0x6a [] simple_dvb_set_params+0x3e/0x9b [] cx22702_set_tps+0x28/0x1d0 [] dvb_frontend_swzigzag_autotune+0x190/0x1b7 [] dvb_frontend_swzigzag+0x1bc/0x21e [] dvb_frontend_thread+0x356/0x43a [] ? dvb_frontend_thread+0x0/0x43a [] kthread+0x49/0x76 [] child_rip+0xa/0x11 [] ? kthread+0x0/0x76 [] ? child_rip+0x0/0x11 Code: 8b 45 c0 31 d2 44 8b 48 1c 48 8b 05 bc 2d 4b 00 44 89 c9 0f b7 40 0a d1 e9 03 45 d0 03 0d ba 2d 4b 00 69 c0 24 f4 00 00 8d 04 01 <41> f7 f1 8a 55 d6 41 89 c4 88 53 04 c1 e8 08 44 88 63 02 88 43 RIP [] simple_dvb_calc_regs+0x9c/0x227 RSP ---[ end trace f8338edded65e015 ]--- So i tried another configuration according to the Gentoo Wiki and it still fails : CONFIG_DVB=y CONFIG_DVB_CORE=y CONFIG_DVB_CX22700=m CONFIG_DVB_CX22702=y CONFIG_VIDEO_CX88_VP3054=m CONFIG_VIDEO_CX88=m CONFIG_VIDEO_CX88_ALSA=m CONFIG_VIDEO_CX88_DVB=m CONFIG_VIDEO_CX88_DVB_ALL_FRONTENDS=y So i'm stuck in an "old" 2.6.27-rc4 since i can't get my card working on newer kernels.
