Have you let the kernel developers know about this bug? Posting on random message boards isn't the best way to get kernel bugs fixed.

The 2.6.21 kernel is out Posted Apr 27, 2007 4:40 UTC (Fri) by h2 (guest, #27965) [Link] I wouldn't call lwn.net a random message board. But I'll be posting this one to bugzilla as soon as I get around to it. I was actually amazed to see this one slip through, this isn't obscure stuff here, and it's not subtle, has been present in all versions I've tested of 2.6.21, so obvious that I was sure that it would have gotten handled.

Even obvious stuff has to be reported by someone.

Re esata not being obvious, I don't know about that, but I guess that kernel devs and testers aren't using it yet. I definitely wish I'd filed a bug report 3 weeks ago, since this was there then too, the actual reason I didn't was that the kernel freeze was so instant that I couldn't get any meaningful logs at all post freeze, which I assumed the kernel guys would need to see.
Esata + usb drives will replace usb standard once people start to realize how absurdly fast they are, once you run this stuff you'll never use usb again if you can help it. It's amazing to see what market inertia looks like though.
And esata is getting more and more commong to run external commercial level drive enclosures too, think for example 3ware.
The 2.6.21 kernel is out Posted Apr 27, 2007 22:30 UTC (Fri) by hawk (subscriber, #3195) [Link] Yes, combined eSATA + USB2.0 external drives are becoming somewhat common and the eSATA interface is, as you said, just so much faster than USB2.0 that once it really catches on, USB2.0 will probably be more or less obliterated when it comes to external storage.
About 25 MB/s for sequential reads vs the full speed of the actual drive (something like a 60 MB/s avg. for sequential reads on a typical disk), the choice should be pretty simple.
That combined with eSATA equipped motherboards being rather common now and one would think that things should start to happen pretty soon.
The 2.6.21 kernel is out Posted Apr 27, 2007 17:31 UTC (Fri) by iabervon (subscriber, #722) [Link] I think esata is more obscure than you think. All the external removable drives I've seen lately have been USB 2.0. Wouldn't be surprised if there were nobody other than you testing -rc kernels with esata at all, since "hardware support for replacing drives" and "it's okay if the computer crashes some" isn't a common combination.
