Hello... I'm running 2.2.5 on a Compaq AP200 with an AHA-2940UW (for the boot drive) and a QLA2100F for connectivity to an external storage device (an EMC Symmetrix 3930). I have the Qlogic card installed as a module and insmod'd it. When I do a dd (like #dd if=/dev/sdb of=/dev/null bs=16384 count=500) or try to send I/O to the external storage via an app called Iorate, I get the message below and the system freezes. Any suggestions are greatly appreciated. Thanks! Heather
