[alsa-devel] Intel ICH Modem init fails for laptop built-in SiS modem
My JVC mininote laptop has an inbuilt SiS modem
00:01.6 Modem [0703]: Silicon Integrated Systems [SiS] AC'97 Modem Controller [1039:7013] (rev a0)
which is detected by the snd-intel8x0m driver but it always fails to initialise and spams the log file :-
kernel: codec_semaphore: semaphore is not ready [0x1][0x1300] kernel:last message repeated 2 times kernel: codec_semaphore: semaphore is not ready [0x1][0x300] kernel:last message repeated 431 times kernel: AC'97 1 does not respond - RESET kernel: codec_semaphore: semaphore is not ready [0x1][0x300] kernel: codec_semaphore: semaphore is not ready [0x1][0x300] kernel: AC'97 1 access is not valid [0xffffffff], removing mixer. kernel: Unable to initialize codec #1 kernel: ACPI: PCI interrupt for device 0000:00:01.6 disabled kernel: Intel ICH Modem: probe of 0000:00:01.6 failed with error -5
I never use the modem so I blacklisted the snd-intel8x0m module in modprobe.conf just to make the messages go away.
I'm currently running the fedora 2.6.23 kernel but it has been broken for a long time.
Is this fixable? or shall I just go on ignoring it ;) ? cheers Richard

The latter unless you really need the support of it ;) We have no datasheet for this SIS chipset, so it's hard to fix, unfortuantely.

Right, thanks.
In that case should we remove it from then supported devices list ?
[ from intel8x0m.c ]
MODULE_SUPPORTED_DEVICE("{{Intel,82801AA-ICH}," ... "{SiS,7013}," ... "{AMD,AMD768}}");

Maybe. But it might work on other machines with the same chipset. It can't be confirmed easily...

OK. But spamming the log with 400+ messages just because it _might_ work somewhere seems wrong to me, when we know it doesn't work on this particular chip.
kernel: codec_semaphore: semaphore is not ready [0x1][0x300] kernel:last message repeated 431 times
isn't there any way to blacklist this particular variant of the chip in the driver ? OTOH maybe just rate limiting the output from code_semaphore would be good enough ?
