USB mass storage I/O operations fail if gpilotd is being used at the same time
Last modified: 2015-01-04 17:15:48 EST
Description of problem: Usb mass storage drives become unusable (cannot copy files, sometimes the system hangs) if gpilotd (gnome-pilot package) is being used at the same time. This seems to be a kernel-related problem, most probably due to a Fedora-specific kernel patch. Version-Release number of selected component (if applicable): Affects a number of kernels including the latest stable one at the time of writing (2.6.10-1.9_FC2). gnome-pilot 2.0.10 is being used. How reproducible: Most i/o operations on a usb mass storage while gpilotd runs will fail. Steps to Reproduce: 1. Start gpilotd (I do that from the applet), make sure it's up and running (eg. HotSync). 2. Now insert into another USB port a usb-storage drive (eg. a USB pen drive or a card reader. I have this problem both with my 64mb pen and my 4-in-1 card reader). 3. Mount, and do a time-consuming operation, like copying an mp3 (like 5 megs or so). The copy will fail, you'll have to umount and remount everything. Actual results: The copy will fail. Expected results: The copy should succeed. Additional info: David A. Desrosiers, part of the GNOME team, has written about this bug (also listed at http://bugzilla.gnome.org/show_bug.cgi?id=164367): "In this case, your bug[1] looks like a kernel bug, not a GNOME bug, and certainly not a gnome-pilot bug. There have been reported issues with the FC2 and FC3 kernels prematurely removing or crashing the USB interfaces on many machines, and it looks like you are seeing the same exact issue. The solution so far (discovered by me) is to back down to the _667 version of the 2.6.9 kernel (if FC3) or recompile your kernel from upstream kernel sources, using the stock config file found in /boot on your Fedora machine. This skips all of the patches that are applied, one of which is causing the problem. I've personally seen this work on at least 6 user's machines in the last 2 months." The relevant dmesg error seems this one: scsi: Device offlined - not ready after error recovery: host 4 channel 0 id 0 lun 2 "uname -a"'s output: Linux localhost.localdomain 2.6.10-1.9_FC2 #1 Thu Jan 13 17:54:57 EST 2005 i686 athlon i386 GNU/Linux "yum info gnome-pilot"s output: Looking in Installed Packages: Name : gnome-pilot Arch : i386 Version: 2.0.10 Release: 6.1 Size : 1.39 MB Group : Applicazioni/Comunicazioni Repo : Locally Installed -- Silvio Moioli moio AT tiscali DOT it (no HTML email please!) http://www.moioli.tk "Things should be as simple as possible, but not any simpler" (A.

Fedora Core 2 has now reached end of life, and no further updates will be provided by Red Hat. The Fedora legacy project will be producing further kernel updates for security problems only. If this bug has not been fixed in the latest Fedora Core 2 update kernel, please try to reproduce it under Fedora Core 3, and reopen if necessary, changing the product version accordingly. Thank you.
