Unmounting ipod

This happens to me too.
The ipod partitions are umounted but not ejected.

Running "sudo eject /dev/sda" works but
also reboots my ipod...

Thanks for you bug? Seems to be the eject bug #11517. What happen if you run
"eject ..." on the device?

from "strace eject /dev/sdb"
...
open("/dev/sdb", O_RDONLY|O_NONBLOCK) = 3
ioctl(3, CDROMEJECT, 0x804d878) = -1 EIO (Input/output error)
ioctl(3, SG_GET_VERSION_NUM, 0xbfea8610) = 0
ioctl(3, SG_IO, 0xbfea8204) = -1 EPERM (Operation not permitted)
ioctl(3, FDEJECT, 0x804d878) = -1 EINVAL (Invalid argument)
ioctl(3, MGSL_IOCGPARAMS or MTIOCTOP or SNDCTL_MIDI_MPUMODE, 0xbfea7a04) = -1
EINVAL (Invalid argument)
...
write(2, "eject: unable to eject, last err"..., 53eject: unable to eject, last
error: Invalid argument

From "sudo strace eject /dev/sda"
open("/dev/sdb", O_RDONLY|O_NONBLOCK) = 3
ioctl(3, CDROMEJECT, 0x804d878) = -1 EIO (Input/output error)
ioctl(3, SG_GET_VERSION_NUM, 0xbfda3620) = 0
ioctl(3, SG_IO, 0xbfda3214) = 0
ioctl(3, SG_IO, 0xbfda3214) = 0
ioctl(3, SG_IO, 0xbfda3214) = 0
ioctl(3, BLKRRPART

At this point the ipod is "ejected", it reboots and it gets mounted again. The
eject command sometimes hangs.. (I can C-c it).

So it seems really the same bug.. (i'm on i386 too).

I also observe this behavior with my iPod shuffle.

The error output is the same as the text that 'eject /dev/sda2' gives me if I
don't sudo. Is the eject command simply running with the wrong privilege?

Btw, this is the only wrinkle left using my iPod, I had many other problems
mounting and unmounting before.

same issue than #5049
