[Michal Semler]

Hi,

for testing purposes I compiled 2.6.12-rc5 and my dmesg si full of 

codec_semaphore: semaphore is not ready [0x1][0x701300]
codec_read 1: semaphore is not ready for register 0x54
codec_semaphore: semaphore is not ready [0x1][0x701300]
codec_write 1: semaphore is not ready for register 0x54
codec_semaphore: semaphore is not ready [0x1][0x700300]
codec_write 0: semaphore is not ready for register 0x2c

Do you mean a regression?  Or just a non-working device?

Non working device.

Semaphore warning is fixed in ALSA CVS (but i still get NO DIALTONE/NO
CARRIER error for this modem).

It is likely not a driver problem, but modem sw (slmodem I guess) -
the device dma should work for 'NO DIALTONE'.
For sure drop please output of
'cat /proc/asound/card1/codec97#0/mc97#1-1' .

This one is supported. The problem is most likely with user-space
slmodem, try recent one (2.9.9d) from
http://linmodems.technion.ac.il/packages/smartlink .

And there are linmodems related list discuss@linmodems.org .

This one (register 0x54) should be fixed in ALSA CVS.

And this is something new. What is output of
'cat /proc/asound/card1/codec97#0/mc97#1-1' ?

Fine, this codec is supported. 

Semaphore warning (both 0x54 and 0x2c) should be fixed in ALSA CVS.
