Public bug reported: I have one of these cards - Marvell 88SE6480 chip I believe, BIOS version is 3.1.0.15N.
I'm booting off a Lucid desktop usb boot drive. Also tried with rescue mode on a Lucid 64 bit server usb key. Machine boots off USB fine and I can partition 4 1TB SATA Hitachi drives attached to the controller with a breakout cable. After installing mdadm, (apt-get install mdadm) I create a new md device as follows: mdadm --create /dev/md0 --raid-devices=2 --spare-devices=2 --level=1 /dev/sda1 /dev/sdb1 /dev/sdc1 /dev/sdd1 That normally completes fine but looking at /proc/mdstat the resync quickly slows to a halt and then I get the following logged repeatedly in dmesg: [ 591.992563] /build/buildd/linux-2.6.32/drivers/scsi/mvsas/mv_sas.c 1608:mvs_query_task:rc= 5 Eventually I start getting errors logged that imply the drives are faulty. Which drive it chooses to say is faulty varies from boot to boot. The drives came from a working machine and have about 6 months on them. I'm confident there's no problem with them. After it picks a drive to fail, I get the following in dmesg: [ 560.988051] sd 3:0:0:0: [sdb] Unhandled error code [ 560.988055] sd 3:0:0:0: [sdb] Result: hostbyte=DID_OK driverbyte=DRIVER_TIMEOUT [ 560.988060] sd 3:0:0:0: [sdb] CDB: Read(10): 28 00 00 00 6a 3f 00 00 08 00 [ 560.988076] end_request: I/O error, dev sdb, sector 27199 I've found several threads on the kernel mailing list about this - but no resolution. The server is currently waiting to go in to production, so I've got a window where I can run any tests required to resolve.
