Jose, Thanks for the pointer to your patch. The bit that disables msi helped. Have either of you (or anyone else) tested with NCQ capable drives? With NCQ enabled, I can get no more than a few minutes out of a stress test before one or more of the drives hang and disconnect. This is with both WD2500JS and Seagate 7200.10 drives. If I black list the drives or add AHCI_FLAG_NO_NCQ to the Marvell port info entry the drives will pass an 8 hour stress test without error. Thanks...george ------------------------------------------ I'm trying Jeff Garzik's preliminary Marvell 6145 SATA support patch and getting nowhere so I'm just checking to see if anyone has got it working or if there have been any further developments. Basically, I'll get "failed to IDENTIFY" messages for each of the drives when the module loads. If I disable MSI (per Jeff's comments) or use irqpoll I can get by those but ultimately under any kind of stress, the drives throw errors...

I can plug them into the ICH7 ports and beat them up for hours. I can also boot to Windows and run the drives flat out on the Marvell without problem. Jumpering the drives back to 1.5g doesn't help. Any ideas or am I just jumping the gun trying to get this to work now?
