Comment # 1 on bug 1006386 from Takashi Iwai

Is this a regression from the previous kernels?  And how reliably is it
reproduced?  Does it happen always?

In anyway, could you report this to upstream, bugzilla.freedesktop.org?  Use
DRI / Intel category.  Feel free to add me (tiwai@suse.de) to Cc there. 
Thanks.
