Issue resolved locally, please close. Sorry for wasting your time.
I'll 'fess up to the gory details: The system is raid zero-ed, except for a conventional /boot on one disk. However, the corresponding partition on the other disk seems to have had a snapshot copy of /boot made onto it at some point (it does have a 2.6.26-2-amd64 kernel, but the file date is Nov 2009 cf mid-September 2010 on the unused /boot version). Thing is, the grub device mapping seems to be such that the obsolete copy is the one being booted! Presumably something changed such that newer kernel sound modules loaded from an up-to-date /lib are incompatible with that old kernel What a mess! This'll need sorting out before any upgrade to a stable Etch upgrade for sure! Tim -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
