Sami,
    I don't believe that additional change to initscripts could be
the cause because Fedora Core 2 doesn't support udev. Only Fedora
Core 3 implements that feature and there are reports of the same
problem occuring under it with 6.5.10.

http://marc.theaimsgroup.com/?l=linux-usb-users&m=110564343717762&w=2

I did notice that FC3 seems to be using initscripts-7.93.5 which
still uses hotplug instead of udevsend. However it seems odd that
both forms (dev and udev) seemed to have gotten broken in the same
way. I assume one can't use udevsend if the kernel isn't using udev
right?

Alan,
    I don't see any changes in how Fedora's 2.6.10 kernels are built 
that should effect USB hotplugging. The previous kernel I was using
shows...

grep HOT config-2.6.7-1.494.2.2smp      
CONFIG_HOTPLUG=y
CONFIG_HOTPLUG_PCI=y
# CONFIG_HOTPLUG_PCI_FAKE is not set
CONFIG_HOTPLUG_PCI_COMPAQ=m
# CONFIG_HOTPLUG_PCI_COMPAQ_NVRAM is not set
CONFIG_HOTPLUG_PCI_IBM=m
# CONFIG_HOTPLUG_PCI_ACPI is not set
# CONFIG_HOTPLUG_PCI_CPCI is not set
CONFIG_HOTPLUG_PCI_PCIE=m
CONFIG_HOTPLUG_PCI_PCIE_POLL_EVENT_MODE=y
CONFIG_HOTPLUG_PCI_SHPC=m
CONFIG_HOTPLUG_PCI_SHPC_POLL_EVENT_MODE=y
CONFIG_DM_SNAPSHOT=m
CONFIG_USB_STORAGE_JUMPSHOT=y

and their new 2.6.10 based kernels show...

grep HOT config-2.6.10-1.9_FC2smp
CONFIG_HOTPLUG=y
CONFIG_HOTPLUG_PCI=y
# CONFIG_HOTPLUG_PCI_FAKE is not set
CONFIG_HOTPLUG_PCI_COMPAQ=m
# CONFIG_HOTPLUG_PCI_COMPAQ_NVRAM is not set
CONFIG_HOTPLUG_PCI_IBM=m
CONFIG_HOTPLUG_PCI_ACPI=m
CONFIG_HOTPLUG_PCI_ACPI_IBM=m
# CONFIG_HOTPLUG_PCI_CPCI is not set
CONFIG_HOTPLUG_PCI_PCIE=m
# CONFIG_HOTPLUG_PCI_PCIE_POLL_EVENT_MODE is not set
CONFIG_HOTPLUG_PCI_SHPC=m
# CONFIG_HOTPLUG_PCI_SHPC_POLL_EVENT_MODE is not set
CONFIG_DM_SNAPSHOT=m
CONFIG_USB_STORAGE_JUMPSHOT=y

Is there anything I can modify (without rebuilding the kernel) that
will fire off dmsegs from the kernel for the calls it makes to 
execute /sbin/hotplug? Perhaps I can see some difference in how or
when hotplug is called by the kernel for usb devices?
                 Jack
ps Fedora did switch with 2.6.10 from using usbdevfs to using usbfs
but they modified their initscripts package to handle that change.

what about this initscripts change 8.01 --> 8.03?

-       sysctl -w kernel.hotplug="/sbin/hotplug" >/dev/null 2>&1
+       sysctl -w kernel.hotplug="/sbin/udevsend" >/dev/null 2>&1

usb key oddities with 2.6.10-ac9

[Jack Howarth]

     Is anyone else seeing problems with kernel 2.6.10 and usb keys
under the Gnome desktop? Fedora Core 2 and 3 has just had two kernel
updates to 2.6.10 (using the -ac8 and -ac9 patches respectively). In
each case, the updates seem to have broken the ability of the Gnome
desktop to present a Flash icon when a usb key is inserted. Oddly if
one boots the machine with the flash key inserted, the Flash icon
does appear in the Gnome desktop's Computer folder. However if one
removes and reinserts the key it disappears and doesn't come back.
I see the same kernel messages as I did under 2.6.7 when I insert
the memory key...

and if I add a line to fstab such as...
                                   
/dev/sdd1    /mnt/lexar    vfat             noauto,rw,user 0 0
                                                              
I can manually mount the usb key fine. Do you know if any other distros
are seeing this problem with 2.6.10 or if the breakage is likely specific
to Fedora's kernel builds?

Make sure you have the hotplug notification stuff all enabled in the
kernel. Missing that can produce the symptoms you describe
