Hi, I recently have upgraded my SB Vibra16x to a C-Media Sound Expert and have also upgraded from OSS/Free to Alsa.
Unfortunately at the moment, I'm writing this mail with no sound enabled because as soon as I 'modprobe snd-cmipci', my machine turns into a hell of inestability and runs for a random amount of time until it locks completely. The problem is not related to any software or hardware, as my machine could run for years without a single reboot if alsa modules are not loaded. Sometimes it hangs with galeon, sometimes with evolution, sometimes with xterm, sometimes with 'ps -A', sometimes with xine. It seems not to be any rule. Sometimes, it hangs inmmediatly after the modprobe, sometimes 20 minutes after, sometimes 5, but I'me sure it will hang. The only thing I have guessed is that kernel is being unable to handle a paging request. This problem looks like related to an open bug in the bugs database. I have atached the output of ksyslogd just after the modprobe and before the hang. Please, help me. I don't want to reboot into windows every time I want to listen a mp3. Thanks in advance. After the modprobe: Sep 8 20:15:48 terminus kernel: PCI: Found IRQ 11 for device 00:11.0 Before the hang: Sep 8 20:19:27 terminus kernel: Unable to handle kernel paging request at virtual address 00004018 Sep 8 20:19:27 terminus kernel: printing eip: Sep 8 20:19:27 terminus kernel: c012570d Sep 8 20:19:27 terminus kernel: *pde = 00000000 Sep 8 20:19:27 terminus kernel: Oops: 0002 Sep 8 20:19:27 terminus kernel: CPU: 0 Sep 8 20:19:27 terminus kernel: EIP: 0010:[__remove_inode_page+53/148] Tainted: P Sep 8 20:19:27 terminus kernel: EFLAGS: 00210246 Sep 8 20:19:27 terminus kernel: eax: 00004000 ebx: c11e3280 ecx: c02a9440 edx: 00000002 Sep 8 20:19:27 terminus kernel: esi: c11e3280 edi: 00000002 ebp: 000001d0 esp: c13abf48 Sep 8 20:19:27 terminus kernel: ds: 0018 es: 0018 ss: 0018 Sep 8 20:19:27 terminus kernel: Process kswapd (pid: 5, stackpage=c13ab000) Sep 8 20:19:27 terminus kernel: Stack: 00000000 c012c5fa c11e3280 00000020 c02a9510 000001d0 c02a9510 c13aa000 Sep 8 20:19:27 terminus kernel: 00000c39 00013401 c02a9510 c012c859 c13abfa8 00000014 000001d0 00000020 Sep 8 20:19:27 terminus kernel: c012c8c0 c13abfa8 c02a9510 00000001 c13aa000 00000000 00000007 c13abfa8 Sep 8 20:19:27 terminus kernel: Call Trace: [shrink_cache+722/816] [shrink_caches+93/104] [try_to_free_pages+92/240] [kswapd_balance_pgdat+85/164] [kswapd_balance+22/44] Sep 8 20:19:27 terminus kernel: [kswapd+155/196] [kernel_thread+40/56] Sep 8 20:19:27 terminus kernel: Sep 8 20:19:27 terminus kernel: Code: ff 48 18 8b 53 04 8b 03 89 50 04 89 02 8b 43 10 8b 53 30 c7 Sep 8 20:19:27 terminus kernel: <1>Unable to handle kernel NULL pointer dereference at virtual address 00000000 Sep 8 20:19:27 terminus kernel: printing eip: Sep 8 20:19:27 terminus kernel: c0114b29 Sep 8 20:19:27 terminus kernel: *pde = 00000000 Sep 8 20:19:27 terminus kernel: Oops: 0000 Sep 8 20:19:27 terminus kernel: CPU: 0 Sep 8 20:19:27 terminus kernel: EIP: 0010:[__wake_up+57/220] Tainted: P Sep 8 20:19:27 terminus kernel: EFLAGS: 00210006 Sep 8 20:19:27 terminus kernel: eax: c11e70a0 ebx: 00000000 ecx: 00000001 edx: 00000003 Sep 8 20:19:27 terminus kernel: esi: c11e70a8 edi: 00000006 ebp: c0b05e20 esp: c0b05e00 Sep 8 20:19:27 terminus kernel: ds: 0018 es: 0018 ss: 0018 Sep 8 20:19:27 terminus kernel: Process xine (pid: 1011, stackpage=c0b05000) Sep 8 20:19:27 terminus kernel: Stack: c11e30a4 c11e3080 00000006 c11e30a8 c11e70a0 00000001 00200282 00000003 Sep 8 20:19:27 terminus kernel: 000001d2 c012619e c78b5b00 c012c61c 00000020 c02a9510 000001d2 c02a9510 Sep 8 20:19:27 terminus kernel: c0b04000 00000c7d 00013995 c02a9510 c012c859 c0b05e84 00000014 000001d2 Sep 8 20:19:27 terminus kernel: Call Trace: [unlock_page+54/56] [shrink_cache+756/816] [shrink_caches+93/104] [try_to_free_pages+92/240] [balance_classzone+67/380] Sep 8 20:19:27 terminus kernel: [_wrapped_alloc_pages+397/660] [add_to_page_cache_unique+109/116] [__alloc_pages+15/140] [page_cache_read+143/224] [generic_file_readahead+273/328] [__do_generic_file_read+460/1152] Sep 8 20:19:27 terminus kernel: [generic_file_read+128/304] [file_read_actor+0/156] [sys_read+150/228] [system_call+51/64] Sep 8 20:19:27 terminus kernel: Sep 8 20:19:27 terminus kernel: Code: 8b 03 85 45 fc 0f 84 7f 00 00 00 31 c0 9c 5f fa c7 03 00 00 ------------------------------------------------------- In remembrance www.osdn.com/911/ _______________________________________________ Alsa-user mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/alsa-user
