Hi all. First of all, sorry for reporting here and not in Alsa-project bug tracking system, but I'm not able to register there (I've registered, but the server hasn't sent me a password). I have problem with alsa-driver-1.0.11, when I compile with vanilla-sources-2.6.15.1 the driver snd-intel8x0 makes kernel oops. Can you anyone pass this error to Alsa team or tell me, where can be some problem? I have motherboard GA-K8N-SLI with nVidia sound (driver snd-intel8x0). If you need, I will copy lspci or other dump of system config.

I don't know much about kernel oopses. But I do know that I get an kernel oops when unloading ALSA modules from the kernel. I use suspend2-sources 2.6.16-r4 and alsa-drivers 1.0.11. Using suspend2-sources 2.6.15-r8 and alsa-drivers 1.0.10 everything seemed to work alright. Since the oops seems to be somewhat different, here's my one: [17179633.260000] Oops: 0000 [#1] [17179633.260000] PREEMPT [17179633.260000] Modules linked in: ipt_MASQUERADE iptable_nat ip_nat iptable_mangle xt_tcpudp xt_state iptable_filter ip_tables x_tables snd_pcm_oss snd_mixer_oss snd_seq_dummy snd_seq_oss snd_seq_midi_event snd_seq snd_via82xx snd_mpu401_uart snd_rawmidi snd_seq_device snd_intel8x0 snd_ac97_codec snd_ac97_bus snd_pcm snd_timer snd snd_page_alloc rtc it87 hwmon_vid eeprom i2c_dev i2c_isa i2c_viapro svgalib_helper nvidia i2c_core [17179633.260000] CPU: 0 [17179633.260000] EIP: 0060:[<e2232e00>] Tainted: P VLI [17179633.260000] EFLAGS: 00010202 (2.6.16-suspend2-r4 #5) [17179633.260000] EIP is at snd_pcm_oss_proc_free_setup_list+0x20/0x50 [snd_pcm_oss] [17179633.260000] eax: 00000003 ebx: 64627573 ecx: dee58a20 edx: dffef300 [17179633.260000] esi: 64627573 edi: dec2fcdc ebp: d8d41f0c esp: d8d41efc [17179633.260000] ds: 007b es: 007b ss: 0068 [17179633.260000] Process rmmod (pid: 9969, threadinfo=d8d40000 task=d90b8a90) [17179633.260000] Stack: <0>de63bee0 dec2fcdc 00000000 bffb22c0 d8d41f20 e2233377 dec2fcdc dec2fc00 [17179633.260000] e22387ec d8d41f38 e223360e dec2fc00 d8d41f58 d9dbf6fc dec2fc04 d8d41f58 [17179633.260000] e215397a dec2fc00 e2238ac0 00000000 e223620a e22387ec 00000001 d8d40000 [17179633.260000] Call Trace: [17179633.260000] [<e2233377>] snd_pcm_oss_proc_done+0x47/0x50 [snd_pcm_oss] [17179633.260000] [<e223360e>] snd_pcm_oss_unregister_minor+0x3e/0x70 [snd_pcm_oss] [17179633.260000] [<e215397a>] snd_pcm_notify+0x4a/0xb0 [snd_pcm] [17179633.260000] [<e223620a>] alsa_pcm_oss_exit+0x1a/0x1c [snd_pcm_oss] [17179633.260000] [<c0134bde>] sys_delete_module+0x14e/0x160 [17179633.260000] [<c015de00>] sys_munmap+0x50/0x80 [17179633.260000] [<c01031c5>] syscall_call+0x7/0xb [17179633.260000] Code: de 8d 76 00 8d bc 27 00 00 00 00 55 89 e5 57 56 53 83 ec 04 8b 7d 08 8b 77 14 85 f6 74 28 c7 47 14 00 00 00 00 8d b6 00 00 00 00 <8b> 5e 10 8b 06 89 04 24 e8 03 6b f3 dd 89 34 24 89 de e8 f9 6a [17179633.260000] /etc/init.d/alsasound: line 137: 9969 Speicherzugriffsfehler /sbin/rmmod ${MODULE} >&/dev/null After oops my computer does not hang, and I tried to get the console with the oops-dump to work again. Strangely there was absolutely no way of killing the hanging rmmod. Not even signal 9 worked. I do not know whether this is an issue of the kernel (suspend2) or alsa. In case I'm reporting to the false person I'm begging your pardon. Thanks for the good work so far!
Got the same problem here using alsa-driver-1.0.11 with any stable gentoo-sources 2.6.16. Everything went just fine. System is booting, modules are loaded and sound is playing.
