I did use modprobe -r sbp2, but I've repeated it (modprobe -r sbp2; modprobe sbp2 serialize_io=1) and everything works much better (no crashes, slow transfers or transfer lockups with either drive). I agree that it was more likely something to do with device addition or removal. Can anyone point me to where sbp2 is loaded in Suse 9.3 so that I can have these parameters added automatically? I've checked some hotplugging web pages but they mostly refer to kernel 2.4, and even then I can't find an explicit 'modprobe sbp2' in the /etc/hotplug* directories. Steffen |
