Same here.
Is your machine smp ?
Do you have preemptive syscalls enabeld ?
Do you use linuxthreads or nptl ?
If you need a quick fix use the kernel scanner-driver of linux-2.6,
_not_ libusb, and install backends-1.0.12.
I tested backends-1.0.12 with libusb and it may damage the mechanics of your epson-scanner.
