nice, please check out 2.6.23-rc7 from trunk and see if it makes a difference, see apt lines -> http://wiki.debian.org/DebianKernel if aboves makes *no* progress, then please holler upstream in bugzilla.kernel.org and let us know the upstream bug number. debian carries no scsi specific patches, although the changer was long time such a boy. best regards -- maks -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
