[alsa-devel] AC97 reset fail after suspend

Hi,

I've got following error on Palm LifeDrive and PalmTX after suspend & resume:

pxa2xx_ac97_try_warm_reset: warm reset timeout (GSR=0x0) pxa2xx_ac97_read: read error (ac97_reg=0 GSR=0x0) pxa2xx_ac97_try_cold_reset: cold reset timeout (GSR=0x44) pxa2xx_ac97_read: read error (ac97_reg=0 GSR=0x44) WM9712 AC97 reset failed could not reset AC97 codec

That completely disable whole AC97 communication, so touchscreen, sound and battery doesn't work any longer.

I also tried this with Treo680 (code will be sent soon). HW is very similar, only codec is different - LD/T5/TX use WM9712, Treo680 use WM9713. On Treo680 there is no problem with that.

Thanks for any hint about that.
