It's safe to say that when 8.3-RELEASE comes out if this problem haunts you again, you will be mailing the list about it, and this cycle will continue until 9.0-RELEASE comes out. Does any developer/committer have familiarity with this issue and have some ideas as to what may have changed in CURRENT that addresses David's issue? And if so, can that code be MFC'd safely or patches provided to David for RELENG_8 that he can try out? I'm CC'ing mav@ here (snd_hda(4) says he's one of the authors), although he may not have any knowledge of the code which may need to be MFC'd. He may be able to point us to who has a better idea though. -- | Jeremy Chadwick [EMAIL PROTECTED] | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
