--- Comment #26 from Robert Richmond <[email protected]> 2012-10-18 18:51:35 --- I originally came to this bug because of a kernel segfault I was receiving during boot, around the time iTCO_wdt was being initialized. It would come up correctly, but the sound hardware would no longer be detected. The last working kernel is 3.4.6, and I'm stuck running it. I still get the same problem in 3.6.1. If I should open a separate bug, let me know. >From 3.4.6: [ 15.712849] iTCO_vendor_support: vendor-support=0 [ 15.848964] parport_pc 00:07: reported by Plug and Play ACPI [ 15.849026] parport0: PC-style at 0x378 (0x778), irq 7 [PCSPP,TRISTATE] [ 15.858862] iTCO_wdt: Intel TCO WatchDog Timer Driver v1.07 [ 15.858933] iTCO_wdt: Found a ICH7 or ICH7R TCO device (Version=2, TCOBASE=0xf860) [ 15.859177] iTCO_wdt: initialized. heartbeat=30 sec (nowayout=0) [ 15.999353] leds_ss4200: no LED devices found [ 16.347091] ppdev: user-space parallel port driver [ 17.218171] EDAC MC: Ver: 2.1.0 [ 17.278506] EDAC MC0: Giving out device to 'i82975x_edac' 'i82975x': DEV 0000:00:00.0 [ 22.118973] snd_hda_intel 0000:00:1b.0: irq 45 for MSI/MSI-X [ 22.491165] hda_codec: ALC262: SKU not ready 0x411111f0 [ 22.491172] ALSA sound/pci/hda/hda_codec.c:5101 autoconfig: line_outs=1 (0x15/0x0/0x0/0x0/0x0) type:line [ 22.491175] ALSA sound/pci/hda/hda_codec.c:5105 speaker_outs=1 (0x16/0x0/0x0/0x0/0x0) [ 22.491178] ALSA sound/pci/hda/hda_codec.c:5109 hp_outs=1 (0x1b/0x0/0x0/0x0/0x0) [ 22.491180] ALSA sound/pci/hda/hda_codec.c:5110 mono: mono_out=0x0 [ 22.491182] ALSA sound/pci/hda/hda_codec.c:5114 inputs: [ 22.491184] ALSA sound/pci/hda/hda_codec.c:5118 Rear Mic=0x18 [ 22.491186] ALSA sound/pci/hda/hda_codec.c:5118 Front Mic=0x19 [ 22.491188] ALSA sound/pci/hda/hda_codec.c:5118 Line=0x1a [ 22.491190] ALSA sound/pci/hda/hda_codec.c:5118 CD=0x1c [ 22.491192] ALSA sound/pci/hda/hda_codec.c:5118 Aux=0x14 [ 22.491194] ALSA sound/pci/hda/hda_codec.c:5120 [ 22.493225] ALSA sound/pci/hda/patch_realtek.c:1317 realtek: No valid SSID, checking pincfg 0x411111f0 for NID 0x1d [ 22.493228] ALSA sound/pci/hda/patch_realtek.c:1400 realtek: Enable default setup for auto mode as fallback [ 22.504829] input: HDA Intel Line as /devices/pci0000:00/0000:00:1b.0/sound/card0/input7 [ 22.504944] input: HDA Intel Front Mic as /devices/pci0000:00/0000:00:1b.0/sound/card0/input8 [ 22.505016] input: HDA Intel Rear Mic as /devices/pci0000:00/0000:00:1b.0/sound/card0/input9 [ 22.505099] input: HDA Intel Front Headphone as /devices/pci0000:00/0000:00:1b.0/sound/card0/input10 [ 22.505168] input: HDA Intel Line Out as /devices/pci0000:00/0000:00:1b.0/sound/card0/input11 >From 3.6.1: [ 16.011433] EDAC MC: Ver: 3.0.0 [ 16.160660] parport_pc 00:07: reported by Plug and Play ACPI [ 16.160713] parport0: PC-style at 0x378 (0x778), irq 7 [PCSPP,TRISTATE] [ 16.207798] general protection fault: 0000 [#1] SMP [ 16.207916] Modules linked in: i82975x_edac(+) parport_pc(+) edac_core coretemp parport microcode(+) serio_raw vhost_net nfsd tun macvtap macvlan auth_rpcgss nfs_acl kvm_intel kvm lockd sunrpc binfmt_misc uinput hid_logitech_dj wmi [ 16.208508] CPU 0 [ 16.208508] Pid: 389, comm: udevd Not tainted 3.6.1-1.fc17.x86_64 #1 Hewlett-Packard HP xw4400 Workstation/0A68h [ 16.208508] RIP: 0010:[<ffffffff812dffe8>] [<ffffffff812dffe8>] strncpy+0x18/0x30 [ 16.208508] RSP: 0018:ffff88013d275b68 EFLAGS: 00010202 [ 16.208508] RAX: ffff8801409bea88 RBX: ffff88013d3d4000 RCX: ffff8801409bea88 [ 16.208508] RDX: 000000000000001f RSI: 5f706f5f63616465 RDI: ffff8801409bea88 [ 16.208508] RBP: ffff88013d275b68 R08: ffff8801409beaa7 R09: 000000000000fffe [ 16.208508] R10: 0000000000000000 R11: ffffffff81161048 R12: 0000000000000003 [ 16.208508] R13: 0000000000000000 R14: ffff8801409be800 R15: ffff88014069f370 [ 16.208508] FS: 00007f8c2bc3c840(0000) GS:ffff880147c00000(0000) knlGS:0000000000000000 [ 16.208508] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 16.208508] CR2: 00007f8c2bc6b000 CR3: 000000013d214000 CR4: 00000000000007f0 [ 16.208508] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 [ 16.208508] DR3: 0000000000000000 DR6: 00000000ffff0ff0 DR7: 0000000000000400 [ 16.208508] Process udevd (pid: 389, threadinfo ffff88013d274000, task ffff88013d162e20) [ 16.208508] Stack: [ 16.208508] ffff88013d275c18 ffffffffa00be6b8 000400003d162e20 ffff88014069f378 [ 16.208508] ffffc90002fa2000 ffff88014069f000 ffff880141bd8000 0000000000000000 [ 16.208508] 0000000000000000 0004000000000000 fed140004009d380 0000000000000246 [ 16.208508] Call Trace: [ 16.208508] [<ffffffffa00be6b8>] i82975x_init_one+0x2e6/0x3e6 [i82975x_edac] [ 16.208508] [<ffffffff81302599>] local_pci_probe+0x79/0x100 [ 16.208508] [<ffffffff81302741>] pci_device_probe+0x121/0x130 [ 16.208508] [<ffffffff813bee4b>] driver_probe_device+0x8b/0x390 [ 16.208508] [<ffffffff813bf1fb>] __driver_attach+0xab/0xb0 [ 16.208508] [<ffffffff813bf150>] ?
