Copy a file from that partition elsewhere Additional info: The computer is an Asus laptop L2400D

Try serialize_io=1 in the module options?
That helped. The Problem disappeared with that option.
The original problem disappeared, but from time to time the sbp2-disks completly disappear while data is copied from or to them. fdisk doesn't show the disks anymore. Disconnecting and reconnecting the disk doesn't help. Two firewire-disks are attached to the system. The hardware is the same, the kernel version is 2.6.6-1.435.2.3.

any better with the latest 2.6.10 updates ?
Fedora Core 2 has now reached end of life, and no further updates will be provided by Red Hat. The Fedora legacy project will be producing further kernel updates for security problems only. If this bug has not been fixed in the latest Fedora Core 2 update kernel, please try to reproduce it under Fedora Core 3, and reopen if necessary, changing the product version accordingly. Thank you.
