Subject: UCB1400 pxa2xx-ac97 failed with error -13 on PXA2xx

Hi, 
I am facing the following problem with ALSA and UCB1400 codec on Colibri PXA270. After having applied Nicolas patches and platform entries in colibri.c, I get the following boot up error messages which annoys me a lot. 
......... 
ts: UCB1x00 touchscreen protocol output
ts: Compaq touchscreen protocol output 
Colibri MMC/SD setup done. 
Advanced Linux Sound Architecture Driver Version 1.0.9rc2  (Thu Mar 24 10:33:39 2005 UTC). 
pxa2xx_ac97_reset: cold reset timeout (GSR=0x0) 
pxa2xx_ac97_reset: warm reset timeout (GSR=0x0) 
pxa2xx_ac97_read: CAR_CAIP already set 
pxa2xx_ac97_write: CAR_CAIP already set 
pxa2xx_ac97_read: CAR_CAIP already set 
pxa2xx_ac97_read: CAR_CAIP already set 
ALSA sound/pci/ac97/ac97_codec.c:1932: AC'97 0 access error (not audio or modem codec) 
pxa2xx-ac97: probe of pxa2xx-ac97 failed with error -13 
ALSA device list: 
  No soundcards found. 
..... 
Can anyone tell me what went wrong and here's the kernel config which I use similar to the previous posts by Takács Áron. 
# 
# Sound 
# 
CONFIG_SOUND=y 
# 
# Advanced Linux Sound Architecture 
# 
CONFIG_SND=y 
CONFIG_SND_TIMER=y 
CONFIG_SND_PCM=y 
# CONFIG_SND_SEQUENCER is not set 
CONFIG_SND_OSSEMUL=y 
CONFIG_SND_MIXER_OSS=y 
CONFIG_SND_PCM_OSS=y 
CONFIG_SND_VERBOSE_PRINTK=y 
CONFIG_SND_DEBUG=y 
# CONFIG_SND_DEBUG_MEMORY is not set 
# CONFIG_SND_DEBUG_DETECT is not set 
# 
# Generic devices 
# 
# CONFIG_SND_DUMMY is not set 
# CONFIG_SND_MTPAV is not set 
# CONFIG_SND_SERIAL_U16550 is not set 
# CONFIG_SND_MPU401 is not set 
CONFIG_SND_AC97_CODEC=y 
# 
# ALSA ARM devices 
# 
CONFIG_SND_PXA2xx_AC97=y 
CONFIG_SND_PXA2xx_PCM=y 
and made the following changes in the colibri.c for platform entries 
static struct platform_device ucb1400_audio_device = { 
.name = "pxa2xx-ac97", 
.id = -1, 
}; 
static struct platform_device *devices[] __initdata = { 
#ifdef CONFIG_DM9000 
    &dm9000_device, 
#endif 
    &ucb1400_audio_device, 
}; 

It would be garteful, if anyone could help me to fix these issues. 
Thanks 
Sara
