Nope, it's more 'load' oriented than 'spot' oriented (i.e. the harder you push them - the more of the above you get)... Both drives are brand new out the box (for what it's worth), so I doub't they're 'bad'... DMA is disabled in the kernel config as well, and the dmesg shows no hints of either multi-block or DMA transfers... Thinking that way I've tried another cable since (brand new out the bag - again 'for what it's worth') - and that has the same symptoms... So does running only 1 drive on the bus... :-( > > I have no love lost for Neptune boards; we have two of them at work, > and it's like trying to work with a 486 board with an OverDrive chip on it. > I'm also wary of Intel boards in general, since they tend to think they're > smarter than you. > True, my second Pentium board was Neptune based (Plato-90?), and it had it's fare share of problems - but to be honest we've had no problems with these ones - their all in AST Premmia GX's - which are the backbone of our business systems at the moment... They work fine, except for this one (which is the only one using IDE). -Kp To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
