Hi

I'm using now 2.6.15-rc5 kernel with latest Alsa 1.0.10 and I received a 
lot of 'bad page state at free_hot_cold_page' (see example below) 
messages. Is this kernel or alsa error?

System:
Slackware Linux, GCC 3.4.4, Binutils 2.16.1.
CPU: Pentium 4 3Ghz HT
Sound card: CMI9880 (HDA)

Regards

	Jacek Luczak
