Description Ed Halley 2004-05-09 16:46:40 UTC

Description of problem:

On first insert of a usb-storage compactflash card reader, the hotplug
scripts properly (mkdir /mnt/flash) and update the fstab.  On unmount
and removal, the hotplug scripts properly reverse this process.

On second and subsequent inserts, hotplug activity seems to run, but
no (mkdir /mnt/flash) and no fstab changes.  The dmesg doesn't seem to
be any different.

Version-Release number of selected component (if applicable):
  kernel 2.6.5-356

How reproducible:
  Every reboot.

Steps to Reproduce:
1.  Reboot system.
2.  Plug usb-storage device.  Note proper /mnt/flash.  Unmount.
3.  Plug usb-storage device again.  Note no /mnt/flash.

Additional Info:
Worked okay on 2.4 kernel series.  Not sure if it's a hotplug,
usb-storage, or kernel issue.

Comment 1 Bill Nottingham 2004-05-21 19:53:14 UTC

Odd. What happens if you manually run updfstab after the second insertion?

Comment 2 Ed Halley 2004-05-21 20:51:15 UTC

Now installed to final FC2 without any additional updates or software.

Running updfstab does the proper (mkdir /mnt/flash) and the device can
then be mounted.

Here is dmesg tail for the first iteration and the second iteration.

First iteration:  insert, mount, examine, umount, yank.

Notice no "usbcore: registered new driver usb-storage" and no "USB

After updfstab, the /mnt/flash was created and mountable.

After umount and yank, "usb 4-2: USB disconnect, address 3".

Comment 3 Lee Wittenberg 2004-09-10 23:07:57 UTC

Modifying the /etc/hotplug/usb.agent file (hotplug-2004_04_01-1) thus:

434a435,437
>     if [ -x /usr/sbin/updfstab ]; then
>         /usr/sbin/updfstab
>     fi

seems to fix the problem.
