The error occurs reproducibly on two identical Opteron servers, each one equipped with two identical controller cards: 03:04.0 SCSI storage controller: Marvell Technology Group Ltd. MV88SX6081 8-port SATA II PCI-X Controller (rev 09) 03:06.0 SCSI storage controller: Marvell Technology Group Ltd. MV88SX6081 8-port SATA II PCI-X Controller (rev 09) We can trigger the problem within a few seconds by starting a reconstruction on a drive hooked to port 4 (counting from 0) of the second controller. Oddly, every other drive works reliably and the faulty drive works if we connect it to, for example, port 4 of the first controller. I'd like to stress that the problem occurs systematically, on two completely distinct machines. We swapped drives, cables and controllers to exclude other possibilities. Tested with Debian kernels 2.6.26-19 and 2.6.30-8. Let me know if further details are needed. -- // Bernie Innocenti - http://codewiz.org/ \X/ Sugar Labs - http://sugarlabs.org/
