I did compile your alsa-driver-unstable using cross-compile powerpc-linnux- in a x86 Linux. Then, I did insmod the modules and aplay -vvv sample.wav. The issue is the same with the old drivers. Following is dmesg : snd-ca0106: Model 100a Rev 00000000 Serial 100a1102 Unable to handle kernel paging request for data at address 0xf0f0f0f4 Faulting instruction address: 0xd10ca7f4 Oops: Kernel access of bad area, sig: 11 [#1] Sequoia Modules linked in: snd_ca0106 snd_ac97_codec ac97_bus snd_seq_oss snd_seq_midi snd_rawmidi snd_seq_midi_event snd_seq snd_seq_device snd_pcm_oss snd_mixer_oss snd_pcm snd_timer snd snd_page_alloc NIP: d10ca7f4 LR: c0059fe8 CTR: d10ca77c REGS: cfaa3d70 TRAP: 0300 Not tainted (2.6.26) MSR: 00029000 <EE,ME> CR: 40008442 XER: 0000005f DEAR: f0f0f0f4, ESR: 00000000 TASK = cf908410[1521] 'aplay' THREAD: cfaa2000 GPR00: f0f0f0f4 cfaa3e20 cf908410 c0ae7040 00000000 4814b000 cfb0a900 00000000 GPR08: 00000000 00004000 00000000 f0f0f0f0 20008448 1002557c 10020000 10020000 GPR16: 10010000 10024a58 00000008 10042050 100406d8 0ff80d50 cfa43a00 00000000 GPR24: 00000000 4814b000 00000000 cf9ff790 00000000 4814b000 cfb0a900 cfaa3e38 NIP [d10ca7f4] snd_pcm_mmap_data_fault+0x78/0xec [snd_pcm] LR [c0059fe8] __do_fault+0x64/0x428 Call Trace: [cfaa3e20] [c004b748] unlock_page+0x48/0x5c (unreliable) [cfaa3e30] [c0059fe8] __do_fault+0x64/0x428 [cfaa3e80] [c000fd88] do_page_fault+0x2e8/0x540 [cfaa3f40] [c000d2ec] handle_page_fault+0xc/0x80 Instruction dump: 80090028 2f800000 419e0074 7c0903a6 4e800421 2c030000 41820048 80030000 7c6b1b78 70094000 40820074 380b0004 <7d200028> 31290001 7d20012d 40a2fff4 ---[ end trace db39fe7fb7fcb01f ]--- Thanks, TaiNguyen On Tue, Aug 26, 2008 at 4:15 PM, nguyen tritai <nguyentritai@xxxxxxxxx>wrote: > Takashi, > > I'm not very familiar with git.
