Summary:                    intel8x0m does not work on asus a3n laptop
Description: 
with this laptop, the sound by intel8x0 works ok, but the modem with the 
alsa-driver intel8x0m and slmodemd 2.9.10 does not.
slmodemd starts ok, it opens the alsa device hw:1 that is tje modem, but
when i try to dial a number (i tried with kppp and minicom) the modem does
dial, but after a while it quits with a NO ANSWER error.
making some exprtiments, i found that when i connect under windows, if i
listen to the phone connected to the same line, i can hear the tones
gererated by the modem, but when i dial under linux i can't hear anything,
so i think this is a driver issue, the driver that can't make the modem
produce any sound.

this is what lspci tells me on that modem:
00:1f.6 Modem: Intel Corp. 82801DB (ICH4) AC'97 Modem Controller (rev 03)

I have similar trouble on roverbook w510L. Errors in log:
semaphore is not ready [0x1][0x701300]
codec_write 1: semaphore is not ready for register 0x54
lspci | grep Modem:
00:1f.6 Modem: Intel Corp. 82801DB (ICH4) AC'97 Modem Controller (rev 03)
It don't work with kernel 2.6.10, 2.6.11.
This modem work with kernel 2.4.29 and slamr driver from Smart Link Ltd.

Don't think it is same - slamr does not work with conexant codec. It is
different problem here.
But "not ready semaphore" should be fixed by this patch:
