Problems ejecting 4th-generation iPod with 2.6.15

Problems ejecting 4th-generation iPod with 2.6.15

[Joshua Kwan]

Hi,

When I plug my iPod in via USB, and later eject it, I more often than
not get this:

usb 5-5: reset high speed USB device using ehci_hcd and address 20
usb 5-5: reset high speed USB device using ehci_hcd and address 20
usb 5-5: reset high speed USB device using ehci_hcd and address 20
usb 5-5: reset high speed USB device using ehci_hcd and address 20
usb 5-5: reset high speed USB device using ehci_hcd and address 20
sd 14:0:0:0: scsi: Device offlined - not ready after error recovery
usb 5-5: USB disconnect, address 20

What's going on here?

A list of other problems that I've seen can be found on Carsten Otto's
site about his own iPod experiences, http://home.c-otto.de/ipod/...

On that page a link to a SuSE ML is linked to, blaming the choice of IO
scheduler, and recommends that people use cfq. I think this is bullshit,
but I am running anticipatory. Should I try cfq?

Thanks,

Can you try 2.6.16-rc5 and let us know if that works better for you
here?

Folks,

On a related note, on my powerbooks here if I do an eject /dev/sda on
the iPod then I get a choice of failure - either the process blocks
and I pull the iPod, or the system locks hard.

Who else is getting weird behavior when they use "eject" and don't just yank it?

Jon.
