[-- Attachment #1 --] Steve, First of all, thank you for taking time with this problem ! Yes, I used the very same machine/controller/cable/enclosure/disks with a live centos system and to check it, and I installed a working debian system on the bay without problem… That's why I'm thinking the key of my problem lives somewhere on src/sys ( well, I don't understand kernel/scsi/sas stuff enought to be sure of this :) The last dmesg were with a CURRENT kernel, I also tested with 11-STABLE and sys/dev/mpr from CURRENT and 11-RELEASE, it looks the same (I saw current mpr(4) seems to have few debugging changes recently) I'll try tomorrow to change one disk with other 2.5' SAS drive to see if they could be the culprits… these ones are "SEAGATE ST2000NX0433 NS02" as reported by "camcontrol devlist", sold (modified ?) by dell. they behave correctly with smartctl, and the error does not block dd command if bs < 128k… not sure what it could mean. Anyway, thank you for your time, and I'd be happy to follow any advice helping to sort out this … (patch, live system, serial debug, …) Yours, Geoffroy.
