I could live without that for the test. If someone could comment on 2.6.28 or 2.6.29, you could avoid running this test. ... > I've replaced the PSU once already - it was replaced on 6th Feb, with a > Sumvision 450W 20+4pin SATA PSU.

It's not just about how many watts. Both 12v and 5v "rails" need to provide enough power. But if this worked before, I would assume the replacement is working too. And in general, yes, a 450W should be plenty for 5 drives plus PMP board. Especially if the OS is "staggering" the spinup so only one or two drives are spinning up at the same time. I know I've had to fix "staggered spinup" in the past (2.6.18) but don't recall if it's fixed in current 2.6.28 or .29 kernels. grant -- To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
