Dear Takashi, Liam, Mark
Thanks for your reply
Hm, this should have been fixed by the later commit: commit 2b39535b9e54888649923beaab443af212b6c0fd Author: Jarkko Nikula jhnikula@gmail.com Date: Fri May 20 15:47:40 2011 +0300
ASoC: core: Don't set "(null)" as a driver nameCould you check whether the segfault occurs at this point? It's possible that another bug was introduced after it, of course.
Hmm... segfault still happen on this commit.
Is this become hint ?
my kernel boot log is
-------------- ... fsi-pcm-audio sh_fsi2: clocks managed by runtime pm ak4642-codec 0-0013: AK4642 Audio Codec 0.0.1 asoc: ak4642-hifi <-> fsia-dai mapping ok sh-mobile-hdmi sh-mobile-hdmi: SH Mobile HDMI Audio Codec asoc: sh_mobile_hdmi-hifi <-> fsib-dai mapping ok ALSA device list: #0: FSI2A (AK4643) #1: FSI2B (SH MOBILE HDMI) --------------
I don't know why, but the segfault didn't happen if I applied below patch
