I have installed alsa-driver with 'ALSA_CARDS="cmipci,ca0106"' in my /etc/make.conf and 'alias snd-card-0 snd-cmipci' in /etc/modules.d/alsa. The module loads OK when I do '/etc/init.d/alsasound start', but when I stop the alsasound daemon I get: Dec 28 19:09:42 basement general protection fault: 0000 [1] Dec 28 19:09:42 basement CPU 0 Dec 28 19:09:42 basement Modules linked in: snd_pcm snd_page_alloc snd_opl3_lib snd_timer snd_hwdep snd_mpu401_uart snd_rawmidi snd_seq_device snd soundcore ipt_ULOG ipt_limit ipt_state ip_conntrack iptable_filter ip_tables rlocate floppy ide_cd cdrom nvidia parport_pc ppa parport us b_storage scsi_mod vfat fat nls_base ohci_hcd nfs 8139too Dec 28 19:09:42 basement Pid: 14508, comm: rmmod Tainted: P 2.6.14-gentoo-r5 #3 Dec 28 19:09:42 basement RIP: 0010:[<ffffffff8016d815>] <ffffffff8016d815>{filp_close+21} Dec 28 19:09:42 basement RSP: 0018:ffff8100096a7ec8 EFLAGS: 00010292 Dec 28 19:09:42 basement RAX: ffff81000ff8b000 RBX: 2f4065766f6d6572 RCX: 0000000000008000 Dec 28 19:09:42 basement RDX: ffff81000ff8b000 RSI: ffff810001a970c0 RDI: 2f4065766f6d6572 Dec 28 19:09:42 basement RBP: 0000000000000000 R08: ffff810001ae4e68 R09: ffff8100096a7ee0 Dec 28 19:09:42 basement R10: 0000000000000001 R11: 0000000000000246 R12: ffff81001e93b640 Dec 28 19:09:42 basement R13: ffff810001a970c0 R14: 0000000000000001 R15: 0000000000000000 Dec 28 19:09:42 basement FS: 00002aaaaade6b00(0000) GS:ffffffff80496800(0000) knlGS:0000000000000000 Dec 28 19:09:42 basement CS: 0010 DS: 0000 ES: 0000 CR0: 000000008005003b Dec 28 19:09:42 basement CR2: 00002aaaaac4d600 CR3: 000000000ab21000 CR4: 00000000000006e0 Dec 28 19:09:42 basement Process rmmod (pid: 14508, threadinfo ffff8100096a6000, task ffff810004fcf0e0) Dec 28 19:09:42 basement Stack: 0000000000000007 0000000000000000 ffff81001e93b640 ffffffff801324db Dec 28 19:09:42 basement 0000000000000000 ffff810004fcf0e0 0000000000000000 0000000000000001 Dec 28 19:09:42 basement 0000000000000880 ffffffff80132d6d Dec 28 19:09:42 basement Call Trace:<ffffffff801324db>{put_files_struct+107} <ffffffff80132d6d>{do_exit+493} Dec 28 19:09:42 basement <ffffffff8013372f>{do_group_exit+159} <ffffffff8010e8a6>{system_call+126} Dec 28 19:09:42 basement Dec 28 19:09:42 basement Dec 28 19:09:42 basement Code: 8b 47 28 45 31 e4 48 89 f5 85 c0 75 10 48 c7 c7 88 7d 34 80 Dec 28 19:09:42 basement RIP <ffffffff8016d815>{filp_close+21} RSP <ffff8100096a7ec8> Dec 28 19:09:42 basement <1>Fixing recursive fault but reboot is needed! This occurs with the stable and testing (~) versions of alsa-driver (ie 1.0.10 and 1.0.10-r1). I've tried recompiling my kernel after a 'make mrproper'.

This affects x86 architectures too: wheat train # cat /proc/asound/version Advanced Linux Sound Architecture Driver Version 1.0.10rc3. Compiled on Dec 28 2005 for kernel 2.6.14.2. wheat train # rmmod snd_cmipci Segmentation fault Worse yet, the module does not work. In an updated system which was previously working, one can hear a faint click when the master volume is changed from 0 to 100%. With the cards unmuted and both PCM and master volumes set to 100% using amixer or alsamixer, aplay claims to be playing a .wav and runs for the correct amount of time, but no sound is heard from the loudspeakers.

Does this happen with 1.0.11_rcs too?
Well, we're now to 1.0.13 final and I didn't hear about this yet, so let's close this.
