I am currently trying to make my new Mantis card running on Gentoo linux with kernel 2.6.25 x86_64. I was able to compile driver (got the latest from site http://jusst.de/hg/mantis) and load modules but when I try to tune it creates kernel OOPS about NULL pointer dereferencing (see the dmesg log below). Thanks for any help. lspci -vvvn: 05:00.0 0480: 1822:4e35 (rev 01) Subsystem: 1ae4:0002 Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx- Status: Cap- 66MHz- UDF- FastB2B- ParErr- DEVSEL=medium >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx- Latency: 64 (2000ns min, 63750ns max) Interrupt: pin A routed to IRQ 16 Region 0: Memory at fafff000 (32-bit, prefetchable) [size=4K] Kernel driver in use: Mantis Kernel modules: mantis dmesg log: Unable to handle kernel NULL pointer dereference at 0000000000000038 RIP: [<ffffffff88026752>] :mantis:philips_cu1216_tuner_set+0x1e/0x264 PGD 0 Oops: 0000 [1] SMP CPU 3 Modules linked in: i2c_i801 cu1216 mantis lnbp21 mb86a16 stb6100 tda10021 tda100 23 stb0899 stv0299 Pid: 5250, comm: kdvb-fe-0 Not tainted 2.6.24-gentoo-r8 #1 RIP: 0010:[<ffffffff88026752>] [<ffffffff88026752>] :mantis:philips_cu1216_tune r_set+0x1e/0x264 RSP: 0018:ffff81006ce13dc0 EFLAGS: 00010293 RAX: 0000000000000000 RBX: ffff81013d2af010 RCX: 0000000000000001 RDX: 0000000000000001 RSI: ffff81013d930808 RDI: ffff81013d2af010 RBP: ffff81013d2af010 R08: 0000000000000000 R09: 0000000000000000 R10: 0000000000000000 R11: 0000000000000000 R12: ffff81013d930808 R13: ffff81013d2af000 R14: 0000000000000003 R15: 0000000000000000 FS: 0000000000000000(0000) GS:ffff81013fab6940(0000) knlGS:0000000000000000 CS: 0010 DS: 0018 ES: 0018 CR0: 000000008005003b CR2: 0000000000000038 CR3: 000000013c412000 CR4: 00000000000006e0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000ffff0ff0 DR7: 0000000000000400 Process kdvb-fe-0 (pid: 5250, threadinfo ffff81006ce12000, task ffff810120139040 ) Stack: 0000000000000286 ffffffff8023c7d1 ffff81006ce12000 ffff81006ce13e30 00000000ffffffff ffff81013d2af010 ffff81013d930808 0000000000000001 ffff81013d2af000 ffffffff8800e543 ffff81013d930800 ffff81013d2af010 Call Trace: [<ffffffff8023c7d1>] lock_timer_base+0x24/0x49 [<ffffffff8800e543>] :tda10023:tda10023_set_parameters+0x36/0x297 [<ffffffff80429834>] dvb_frontend_swzigzag_autotune+0x188/0x1a5 [<ffffffff80429a08>] dvb_frontend_swzigzag+0x1b7/0x216 [<ffffffff80429d63>] dvb_frontend_thread+0x296/0x310 [<ffffffff80246f4d>] autoremove_wake_function+0x0/0x2e [<ffffffff80246f4d>] autoremove_wake_function+0x0/0x2e [<ffffffff80429acd>] dvb_frontend_thread+0x0/0x310 [<ffffffff802469f4>] kthread+0x3d/0x63 [<ffffffff8020c498>] child_rip+0xa/0x12 [<ffffffff802469b7>] kthread+0x0/0x63 [<ffffffff8020c48e>] child_rip+0x0/0x12 Code: 4c 8b 68 38 76 0e 48 c7 c7 5d 98 02 88 31 c0 e8 32 eb 20 f8 RIP [<ffffffff88026752>] :mantis:philips_cu1216_tuner_set+0x1e/0x264 RSP <ffff81006ce13dc0> CR2: 0000000000000038 ---[ end trace 442dec1c5f34bbe9 ]--- -- Stefan Gula CCNP, CCIP _______________________________________________ linux-dvb mailing list linux-dvb@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
