Hi,
Pls check the attached file that is dmesg of a ALSA crash. Can
you pls tell under what conditions this happens?
Another thing ... in pcm_lib.c , for the funtion snd_pcm_update_hw_ptr.
, there is a comment that "this should be called with interrupts
disabled". Can you tell us who is disabling the interrupts just before
this is called?
Does spin_lock_irq do that?
We are using RedHat 7.1 linux on i810 motherboard and the latest version
of ALSA 0.9.0.
Shaju Abraham.
