[2.6.10-rc2] ehci_hcd causes oops after some use of usb harddisk

[Jan De Luyck]

Hello list,

Kernel: 2.6.10-rc2

I'm trying to use an USB harddisk (IDE disk in USB2.0 enclosure) with my linux laptop. Using it at usb-1 speeds with the usb_uhci module causes no problems whatsoever.

When trying to use the drive while claimed with ehci_hcd, it will disconnect after a while, causing my connection to my disk to hang, and the entire USB subsystem with it. (removing modules is no longer possible).

This is after plugging the drive and mounting the XFS filesystem on it:

Then I copy some stuff on it. When the actual write starts (eg triggered with sync), the activity led never goes out anymore.

Shortly thereafter:

while nothing changed to the state of the USB device...

Any hints? This is rather annoying, as I do want to be able to use this at it's full speed...
