Most recent kernel where this bug did not occur: I have never tried the below test before Distribution: SuSE 9.3 Hardware Environment: Laptop Samsung X20, Pentium M 1.6 GHz, 2GB RAM, USB Controller: Intel Corporation 82801FB/FBM/FR/FW/FRW, External USB2 DVD-RW "Freecom Classic" Software Environment: SuSE 9.3 with kernel 2.6.11.4-21.7, patched with patch #5737 (see bug #5010) Problem Description: USB2 mass storages seem to conflict, see "Steps to reproduce" for an exact description. In my case the iPod conflicts with an external DVD drive Steps to reproduce: 0. boot 1. plug in the iPod 2. mount the iPod 3. start data transfer to/from the iPod (I just started xmms to play songs stored on the iPod) 4. plug in the DVD drive 5. after few seconds xmms does not respond any more, as the files to be played are no more accessible. At this point the iPod file system can still be read, "ll /USB" shows the correct file list 6. after about a minute the iPod file system cannot be read any more, "ll /USB" shows just an empty directory Some comments: 1. The problem is not symmetric: if the DVD drive is plugged in first, and the iPod is plugged in after that, everything works fine. 2. The problem seems to be USB2-specific: I tried to replace the iPod by a foto camera (USB1) in the above test sequence, and everything worked.
I am guessing that 2.6.11.4-21.7 is a distro kernel? Please file a bug with a distro or reproduce in 2.6.12.5/2.6.13-rc7. Thanks, Nish
Created attachment 5777 [details] System information relevant to the bug P.S. Sorry, in few hours I'm going offline until 7.09 and will not be able to answer test/info/... requests.
Distro specific bugs should go in distro specific bugzillas. If you can reproduce this on 2.6.13, please reopen it.
