USB harddisk drive fails on 2.6.23-rc3 (regression)

Hi all,

I just bought myself an external hard disk drive for my backups:

$ lsusb
(...)
Bus 002 Device 002: ID 0bc2:3000 Seagate RSS LLC
(...)

I found that I was not able to list the partition table (fdisk -l)
under a 2.6.23-rc3 kernel (let alone change it), while rebooting under
2.6.22.3 the partition table could be read. I finally tracked it down
to CONFIG_USB_SUSPEND=y, when this option is disabled "fdisk -l" works
again on 2.6.23-rc3. I could also get it to work again by reverting
commit 8dfe4b14869fd185ca25ee88b02ada58a3005eaf ("usb-storage: implement
autosuspend") as was reported by other users recently.

Here is the failure log (2.6.23-rc3-git2, CONFIG_USB_SUSPEND=y,
CONFIG_USB_STORAGE_DEBUG=y):

Do I have to add my drive to the USB quirk list (as either
USB_QUIRK_RESET_RESUME or USB_QUIRK_NO_AUTOSUSPEND), or is there a
better way to address the problem?

Thanks,
