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 -- Rolf Offermanns SYSGO AG Tel.: +49-6136-9948-0 Am Pfaffenstein 14 Fax: +49-6136-9948-10 55270 Klein-Winternheim http://www.sysgo.com
