Hi This was originally submitted as bugzilla.kernel.org # 37642. I don't know where to continue followup since that server's demise. to recap previous report: am using the device on a system that was running ubuntu 2.6.38 kernel. where all six drives in this external RAID unit were presented to the operating system without issue. (standard ubuntu 11.04 kernel.) I am not interested in the software raid part, just want to use the external enclosure as JBOD, and use an os based technology for ganging the disks. When upgraded to 11.10, with 3.0.0 kernel, the disks units are no longer recognized. Tejun Heo asked me to try various bios options. they were tried and had no effect. was asked to add a little code to ahci.c to recognize 91a4. It had no effect. kernel version is pinned to old one for now. lspci: 02:00.0 RAID bus controller: HighPoint Technologies, Inc.
