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.
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
The copy will fail.
The copy should succeed.
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 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:

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.
