Hi I tried the two workarounds : 1 - Compile kernels sound system as modules and compile these modules with -O1 instead of default -Os or -O2 (e.g. by changing main Makefile). I modified the makefile : ifdef CONFIG_CC_OPTIMIZE_FOR_SIZE CFLAGS += -O1 else CFLAGS += -O1 endif 2 - patch from Fengwei Yin adding the line mb(); before snd_mask_intersect(mask, v); in the file pcm_params.h But I still have the same problem. I think i did a mistake.... Otherwise, I will wait the next release of gcc or/and the kernel... Sorry for the previous incomplete mail to the mailinglist (a problem with my keyboard ;-) ) Thanks David. -- http://slugplayer.free.fr -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
