Unfortunately, there was an unrelated libata bug which made it where 4 of my drives were not recognized, and since the drive that has this general timeout issue with linux is dedicated to an lvm I depend on those other drives so I can mount the lvm so I can reproduce this bug. What I do know: Good: v2.6.25 Bad: pre v2.6.26-rc1 (9752082560b440e6a45624569d26802e20d1b8b4) Please, How can I help further? -- avuton -- | (\_/) This is Bunny.
