--- Cliff Cai 2009-10-26 04:47:24

this is a problem of mmap,Graf,would you have a look at it?

Thanks

Cliff

--- Graf Yang 2009-10-26 05:04:18

Please reference the following link,

http://mailman.alsa-project.org/pipermail/alsa-devel/2009-March/015802.html

We may need to update to the alsa mainline code.

--- Sonic Zhang 2009-10-27 00:35:39

I think Cliff can import that patch to SVN head before we update to new kernel

version.

--- Cliff Cai 2009-10-29 02:39:45

it works for me,thanks.

--- Vivi Li 2009-11-01 22:27:32

OK now. Close it.
