opl3sa2 sound driver doesn't support `suspend computer'
Last modified: 2005-10-12 19:44:02 UTC
On a Toshiba Tecra 8000, with Suse 10.0 RC??? (I did upgrade from 9.3 through the Web) # rpm -q powersave powersave-0.10.12-2 # rpm -q dbus-1 dbus-1-0.35.2-6 # rpm -q hal hal-0.5.4-4 # uname -r 2.6.13-8-default The opl3sa2 drive works fine from Power Up, with: # cat /etc/modprobe.d/sound options snd-opl3sa2 dma1=1 dma2=1 enable=0 fm_port=0x388 index=0 irq=5 isapnp=0 midi_port=0x330 port=0x538 wss_port=0x530 sb_port=0x220 # :Yamaha OPL3-SA23 alias snd-card-0 snd-opl3sa2 When I configured the sound card, Yast doesn't allow for the value `port=0x538' so I manually edited the modprobe file with a value acceptable by the Tecra BIOS. The problem shows up when suspending the laptop. After waking it up the sound system will receive errors: ALSA write error: Input/output error Thanks!!!
Try to remove all module options for snd-opl3sa2 except for index=0.
I tried that. Now I have: # cat /etc/modprobe.d/sound options snd-opl3sa2 index=0 # :Yamaha OPL3-SA23 alias snd-card-0 snd-opl3sa2 The problem is still there, when waking up from hibernate. Also I didn't mention it in the original bug report, but before seeing the I/O error message (I'm using mpg321 command line tool), I can hear a ratchetting sound, so I suppose that some low level access are going out to the audio chip.
OK, then it's a bug of the driver. Please try to reload the driver after resume, and check whether it works. If it works, we'll have a hope to fix it :) But, I'd like to work on this problem rather on ALSA bugtracking. SUSE/Novell doesn't "support" this driver officially (see "tainted" kernel message).
I tried the rmmod/modprobe ... Might not be a difficult `Oops' to track down, but it's very likely closely tied to the Tecra8000 hardware idiosyncrasies. As the Yast2 menus I used at first to configure the sound chip don't even know about the Hardware addresses used on that laptop, maybe the driver makes a few assumptions. snd_opl3sa2: module not supported by Novell, setting U taint flag. kobject_register failed for opl3sa2-pnpbios (-17) [<c01ee553>] kobject_register+0x43/0x50 [<c025572d>] bus_add_driver+0x4d/0xa0 [<c023240c>] pnp_register_driver+0x2c/0x60 [<c883d72f>] alsa_card_opl3sa2_init+0x4f/0x95 [snd_opl3sa2] [<c0134161>] sys_init_module+0xa1/0x180 [<c0102d1b>] sysenter_past_esp+0x54/0x79 Unable to handle kernel paging request at virtual address c8dedf80 printing eip: c8da8b70 *pde = 0794d067 Oops: 0000 [#1] Modules linked in: snd_opl3sa2 uhci_hcd ipt_pkttype ipt_LOG ipt_limit speedstep_lib freq_table snd_pcm_oss snd_mixer_oss snd_seq_midi snd_seq_midi_event snd_opl3_synth snd_seq_instr snd_seq_midi_emul snd_seq snd_ainstr_fm pcc_acpi sony_acpi toshiba_acpi thermal processor fan button battery ac af_packet edd 3c574_cs pcmcia firmware_class ip6t_REJECT donauboe irda crc_ccitt yenta_socket rsrc_nonstatic pcmcia_core ipt_REJECT ipt_state i2c_piix4 i2c_core usbcore generic iptable_mangle iptable_nat iptable_filter ip6table_mangle ip_conntrack ip_tables ip6table_filter ip6_tables ipv6 parport_pc lp parport snd_opl3_lib snd_hwdep snd_cs4231_lib snd_mpu401_uart snd_rawmidi snd_seq_device snd_pcm snd_timer snd soundcore snd_page_alloc dm_mod reiserfs ide_cd cdrom piix ide_disk ide_core CPU: 0 EIP: 0060:[<c8da8b70>] Tainted: G U VLI EFLAGS: 00010282 (2.6.13-8-default) EIP is at snd_ctl_open+0x40/0xf0 [snd] eax: c8dedf80 ebx: fffffff2 ecx: 0000702c edx: c6232c54 esi: c66d4814 edi: c22da100 ebp: c73f9990 esp: c54b3f00 ds: 007b es: 007b ss: 0068 Process mpg321 (pid: 5884, threadinfo=c54b2000 task=c61dd0a0) Stack: c8db4500 00000000 c22da100 c8da6147 00000000 c76be2e0 00000000 c73f9990 c0160f8e c22da100 ffffffe9 c22da100 c73f9990 c7fe4140 ffffffe9 c01586ae c61d7384 00000000 c6fc5000 00000003 c6fc5000 c01585de c61d7384 c7fe4140 Call Trace: [<c8da6147>] snd_open+0x87/0x150 [snd] [<c0160f8e>] chrdev_open+0x6e/0x130 [<c01586ae>] dentry_open+0xbe/0x1d0 [<c01585de>] filp_open+0x3e/0x50 [<c01588e7>] sys_open+0x37/0xc0 [<c0102d1b>] sysenter_past_esp+0x54/0x79 Code: db c8 85 f6 75 0b bb ed ff ff ff 89 d8 5b 5e 5f c3 89 f0 e8 53 e6 ff ff 85 c0 78 ea 8b 86 34 01 00 00 85 c0 74 14 bb f2 ff ff ff <83> 38 02 0f 84 83 00 00 00 ff 80 00 01 00 00 b9 d0 00 00 00 ba Kernel is: kernel-default-2.6.13-8 Linux rover 2.6.13-8-default #1 Tue Sep 6 12:59:22 UTC 2005 i686 i686 i386 GNU/Linux
The Oops at removing the module was already fixed in the recent version. Try kernel-of-the-day (KOTD) from ftp.suse.com/pub/people/mantel/kotd.
I don't have access to this laptop for the time being. As soon as I get a chance to try, I'll keep you posted. Thanks for your support !!!
I got the laptop back and I re-installed the final 10.0. The problem no longer shows up :-) I suppose that you can close that bug... Thanks for your support !!!
Fixed in GM-10.0
