Description Tvrtko Ursulin 2008-12-04 19:24:33 UTC

This is a regression from v11 and I also suspect it may be a generic 2.6.27 regression since _I think_ I saw that problem on another distro based on 2.6.27, but as at the time I did a lot of shuffling around I can't be sure. But it is sure a regression from v11.

Hardware in question is an external 2.5" HDD enclosure housing a Samsung HDD. As I said it worked fine (and still does) on earlier versions.

Now it gets into a strange state after connecting (I will paste the kernel log later) and does not go out of it until I disconnect it. I will also annotate the disconnection point in the log.

And although I chose 'kernel' as component above it may as well be something else, like something in hotplug chain, which confuses it when there is no partition table (there really isn't). I don't know..

Machine is nothing fancy, here is the lspci output:

Comment 1 Tvrtko Ursulin 2008-12-06 21:00:46 UTC

Looks suspiciously like this bug http://bugzilla.kernel.org/show_bug.cgi?id=11843 ?

Comment 2 Javier Llorente 2008-12-07 17:38:52 UTC

I am also getting the "sense key/no sense" messages when I plug in a USB hard disk on openSUSE 11.1 RC 1. The same USB hard disk works perfectly on openSUSE 11.0

Comment 3 Oliver Neukum 2008-12-08 07:38:37 UTC

Yes, it looks like that issue. I'll check whether the fix will go in through the stable series or needs to be backported.

Comment 4 Oliver Neukum 2008-12-09 12:28:31 UTC

@Javier

Unless it is the same enclosure, please open a new bug report

Comment 5 Oliver Neukum 2008-12-09 12:58:41 UTC

Tvrtko, your device is known as unusual in the current kernel. Please test the latest kernel and provide the output of "lsusb -v" if it doesn't work.

Comment 6 Javier Llorente 2008-12-09 18:10:16 UTC

Same symptoms I guess...
This still happens with the latest kernel.

then same thing with block 34, 35, etc.

I am running 2.6.27.7-4-default from kernel-default-2.6.27.7-4.1.x86_64.rpm which as far as I know is the latest. I'll attach lsusb -v output..

@Javier

Open a separate bug report

Comment 11 Javier Llorente 2008-12-10 11:09:31 UTC

Done.
Bug #457941

Comment 13 Hendrik Vogelsang 2008-12-11 13:45:28 UTC

This hits _a lot_ of usb storage devices (see for instance #264789 in
launchpad) and is a regression from 11.0. Oliver you might want to think about
raising the prio of this...

Comment 14 Oliver Neukum 2008-12-11 14:03:56 UTC

Please test the kernel found at
http://beta.suse.com/private/oneukum/456526

Comment 15 Tvrtko Ursulin 2008-12-11 19:47:35 UTC

Works fine for me. I am now back to published kernel because I need the matching kernel source package so hopefully you don't need any more info here?

Comment 16 Oliver Neukum 2008-12-11 23:00:42 UTC

I fixed this particular one. However that approach seems unproductive. The real cause is a change of error handling in the SCSI layer. Is this issue important enough to consider reverting this change to 2.6.26 behavior?

Comment 17 Hendrik Vogelsang 2008-12-12 15:10:31 UTC

I would say yes but i don't know what other implications that might have. We might want to ask Greg who was involved in the upstream bugreport. Greg? This is about bko#11843.

I have a generic USB enclosure with a 160GB IDE drive that gives the same problem. It worked 100% in openSUSE 11 on the same machine.
