[gentoo-user] Problems with IcyBox external HD with Cypress Chipset

Hi,

Rates of the datatransfers to and from my IceBox external HD (USB to IDE) with Cypress Chipset 
sometimes (relative often) breaks down to a view kBytes/sec.
Simultaneously, mousemovements (USB mouse/Logitech) also start to stutter. The only way out of
this scenario is a reboot. Unloading the according modules leads to
various unwanted sideeffects like total freezes and being unable to
reboot because the shutdown process is not able sync/unmount anymore.

At the time of buying the IcyBox this one was declared to be able to
work with Linux. Since then I had that problems...


My hardware:
IcyBox (USB->IDE, Cypress chipset)
Asus AV8 (Via Chipset)
Linux 2.6.27.10 (vanilla)
kernel config attached

Datatransfers via USB High speed to a for example 4GB UsbStick work
without problems.

Is there any way to circumvent these issues or anything known around
this?

Thank you very much in advance for any help!
Kind regards
Meino Cramer
