Kernel Bug Tracker – Bug 5134
USB2 mass storages conflict
Last modified: 2005-09-02 00:27:05 UTC
Most recent kernel where this bug did not occur:
I have never tried the below test before
Distribution: SuSE 9.3
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"
SuSE 9.3 with kernel 18.104.22.168-21.7, patched with patch #5737 (see bug #5010)
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:
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
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 22.214.171.124-21.7 is a distro kernel? Please file a bug with a
distro or reproduce in 126.96.36.199/2.6.13-rc7. Thanks, Nish

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.
