snd_intel8x0m and semaphore warning

snd_intel8x0m and semaphore warning

[Nickolay V. Shmyrev]

Hi I know there was problems with sound card driver snd_intel8x0, now
very often problem is the same kind of warning with snd_intel8x0m modem
driver:

codec_semaphore: semaphore is not ready [0x1][0x701300]
codec_write 1: semaphore is not ready for register 0x54

My configuration - Toshiba A50 laptop with Fedora Core 3 from box

lspci:

0000:00:1f.6 Modem: Intel Corp. 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M)
AC'97 Modem Controller (rev 03) (prog-if 00 [Generic])
        Subsystem: Toshiba America Info Systems: Unknown device 0001
        Flags: bus master, medium devsel, latency 0, IRQ 11
        I/O ports at 1800 [size=256]
        I/O ports at 1480 [size=128]
        Capabilities: [50] Power Management version 2

cards:

0 [I82801DBICH4   ]: ICH - Intel 82801DB-ICH4
                     Intel 82801DB-ICH4 at 0x18080800, irq 11
1 [Modem          ]: ICH-MODEM - Intel 82801DB-ICH4 Modem
                     Intel 82801DB-ICH4 Modem at 0x1800, irq 11

I am using slmodemd-2.9.10 compiled with alsa support and when I am
dialing to ISP i have warnings above. I am not alone with that problem,
for example, see http://linux.seindal.dk/index.php?itemid=61

Could someone help me in debugging and correcting those warnings?

It's broken, at least in 2.6.10. In my case, if i loaded the modem
driver, the sound one stopped working (with a lot of semaphore
errors...) My solution is not using the modem driver by now :(. I
think that Takashi said that there was a problem in common
initialization in both drivers, so i hope it gets fixed soon ;)
