Hi i have a very recent andy-tracking kernel and i've got an error with the snd module on my GTA01.
Would be nice if someone could have a look at this. It seems to deep for my alsa skills. Here the Log on module load: pcf50606 0-0008: INT1=0x40 INT2=0x00 INT3=0x01 pcf50606 0-0008: adc result = 717 pcf50606 0-0008: INT1=0x00 INT2=0x00 INT3=0x01 pcf50606 0-0008: adc result = 496 pcf50606 0-0008: INT1=0x00 INT2=0x00 INT3=0x01 pcf50606 0-0008: adc result = 537 pcf50606 0-0008: INT1=0x00 INT2=0x00 INT3=0x00 GSM wakeup interrupt (IRQ 17) GSM wakeup interrupt (IRQ 17) rxerr: port=0 ch=0x00, rxs=0x0000000e No device for DAI s3c24xx-i2s Entered neo1973_init pcf50606 0-0008: INT1=0x40 INT2=0x00 INT3=0x01 pcf50606 0-0008: adc result = 716 pcf50606 0-0008: INT1=0x00 INT2=0x00 INT3=0x00 pcf50606 0-0008: INT1=0x00 INT2=0x00 INT3=0x01 pcf50606 0-0008: adc result = 505 pcf50606 0-0008: INT1=0x00 INT2=0x00 INT3=0x01 pcf50606 0-0008: adc result = 523 pcf50606 0-0008: INT1=0x00 INT2=0x00 INT3=0x00 Log on module unload: Unable to handle kernel NULL pointer dereference at virtual address 00000008 pgd = c7b2c000 [00000008] *pgd=37ba4031, *pte=00000000, *ppte=00000000 Internal error: Oops: 817 [#1] PREEMPT Modules linked in: snd_soc_neo1973_wm8753(-) snd_soc_s3c24xx_i2s snd_soc_s3c24xx ipv6 rfcomm hidp l2cap snd_soc_wm8753 snd_soc_core ohci_hcd snd_pcm snd_timer snd_page_alloc snd CPU: 0 Not tainted (2.6.29-GTA01_localandy #2) PC is at mutex_lock+0x10/0x24 LR is at snd_soc_free_pcms+0x24/0x54 [snd_soc_core] pc : [<c02f2280>] lr : [<bf0488a8>] psr: a0000013 sp : c7b33e20 ip : c7b33e30 fp : c7b33e2c r10: 00000000 r9 : c7b32000 r8 : c002cf68 r7 : bf05eea0 r6 : 00000008 r5 : bf0df00c r4 : 00000000 r3 : 00000000 r2 : c714ac08 r1 : 00000004 r0 : 00000008 Flags: NzCv IRQs on FIQs on Mode SVC_32 ISA ARM Segment user Control: c000717f Table: 37b2c000 DAC: 00000015 Process rmmod (pid: 1379, stack limit = 0xc7b32268) Stack: (0xc7b33e20 to 0xc7b34000) 3e20: c7b33e4c c7b33e30 bf0488a8 c02f2280 c7b33e6c bf0df00c bf0df0e4 c714ac00 3e40: c7b33e64 c7b33e50 bf0576d4 bf048894 bf0d0210 bf0d0210 c7b33e84 c7b33e68 3e60: bf049980 bf0576c8 c714ac08 bf050e18 c03f0aa0 c7b33f48 c7b33e94 c7b33e88 3e80: c01d8fb4 bf049940 c7b33eac c7b33e98 c01d7d60 c01d8fa4 c714ac08 c714ac90 3ea0: c7b33ec4 c7b33eb0 c01d7da0 c01d7cfc c714ac08 c714ac38 c7b33edc c7b33ec8 3ec0: c01d7050 c01d7d8c c714ac08 00000000 c7b33efc c7b33ee0 c01d56f8 c01d6fec 3ee0: c7b33f04 c714ac00 00000000 00000000 c7b33f1c c7b33f00 c01d955c c01d5600 3f00: c01d8324 c714ac00 00000000 00000000 c7b33f34 c7b33f20 c01d9908 c01d954c 3f20: bf0df300 bf0df300 c7b33f44 c7b33f38 bf0dd840 c01d9900 c7b33fa4 c7b33f48 3f40: c0070e70 bf0dd830 5f646e73 5f636f73 316f656e 5f333739 37386d77 ff003335 3f60: 00001000 40150000 00012008 00000000 00000000 40025000 c7b33f9c c7b33f88 3f80: 00033eac 00000000 be8b7ba0 00000000 00008800 00000081 00000000 c7b33fa8 3fa0: c002cdc0 c0070d2c be8b7ba0 00000000 be8b7ba0 00000880 00000880 be8b7ba0 3fc0: be8b7ba0 00000000 00008800 00000081 00000000 00000000 40025000 be8b7c14 3fe0: 00000000 be8b7b98 000091cc 400efe3c 60000010 be8b7ba0 00000000 00000000 Backtrace: [<c02f2270>] (mutex_lock+0x0/0x24) from [<bf0488a8>] (snd_soc_free_pcms+0x24/0x54 [snd_soc_core]) [<bf048884>] (snd_soc_free_pcms+0x0/0x54 [snd_soc_core]) from [<bf0576d4>] (wm8753_remove+0x1c/0x2c [snd_soc_wm8753]) r6:c714ac00 r5:bf0df0e4 r4:bf0df00c [<bf0576b8>] (wm8753_remove+0x0/0x2c [snd_soc_wm8753]) from [<bf049980>] (soc_remove+0x50/0xb4 [snd_soc_core]) r4:bf0d0210 [<bf049930>] (soc_remove+0x0/0xb4 [snd_soc_core]) from [<c01d8fb4>] (platform_drv_remove+0x20/0x24) r7:c7b33f48 r6:c03f0aa0 r5:bf050e18 r4:c714ac08 [<c01d8f94>] (platform_drv_remove+0x0/0x24) from [<c01d7d60>] (__device_release_driver+0x74/0x90) [<c01d7cec>] (__device_release_driver+0x0/0x90) from [<c01d7da0>] (device_release_driver+0x24/0x30) r5:c714ac90 r4:c714ac08 [<c01d7d7c>] (device_release_driver+0x0/0x30) from [<c01d7050>] (bus_remove_device+0x74/0x84) r5:c714ac38 r4:c714ac08 [<c01d6fdc>] (bus_remove_device+0x0/0x84) from [<c01d56f8>] (device_del+0x108/0x158) r5:00000000 r4:c714ac08 [<c01d55f0>] (device_del+0x0/0x158) from [<c01d955c>] (platform_device_del+0x20/0x64) r6:00000000 r5:00000000 r4:c714ac00 [<c01d953c>] (platform_device_del+0x0/0x64) from [<c01d9908>] (platform_device_unregister+0x18/0x24) r6:00000000 r5:00000000 r4:c714ac00 [<c01d98f0>] (platform_device_unregister+0x0/0x24) from [<bf0dd840>] (neo1973_exit+0x20/0x2c [snd_soc_neo1973_wm8753]) r4:bf0df300 [<bf0dd820>] (neo1973_exit+0x0/0x2c [snd_soc_neo1973_wm8753]) from [<c0070e70>] (sys_delete_module+0x154/0x1b0) [<c0070d1c>] (sys_delete_module+0x0/0x1b0) from [<c002cdc0>] (ret_fast_syscall+0x0/0x2c) r7:00000081 r6:00008800 r5:00000000 r4:be8b7ba0 Code: e1a0c00d e92dd800 e24cb004 e3a03000 (e1002093) ---[ end trace 4944f792fca78564 ]--- Tim Niemeyer
