PPC440EP (Bamboo) USB freeze - BDI2000 question

Hi all,
I have some problems with a 2.6.12 + Wades patches from 27.07. and John's usb
host patch from 27.07.
I tried different external USB harddisks and card readers and the system
freezes almost every time when doing some transfers (dd if=/dev/zero
of=/dev/scsi/.../disc). Not immediately but after a minute or so.
I attached a BDI2000 (FW 1.14, configs from Denks FTP and the ones that came
with the FW) but I am not able to bring the target to debug mode after the
freeze. This is what I get:
-------------------------------------------------------------------------
440EP>halt
Core number : 0
Core state : running
# PPC: timeout while waiting for freeze
------------------------------------------------------------------------
440EP>stop
Core number : 0
Core state : running
# PPC: timeout while waiting for freeze
-------------------------------------------------------------------------
Strange thing: The freezes are getting less frequent the longer the target is
running and when the BDI is attached it seems to be more difficult to hit the
bug.
Any help is greatly appreciated.
Thanks,
Rolf
