| |
I've tried to use my external Imation SuperDisk parallel port drive in Linux 2.6.12 but failed. The drive is detected properly but when I try to mount a floppy, I get errors (they look like timeouts), the system is unresponsive (even framebuffer cursor stops blinking) and then it oopses (see below). Also when I configure the port to ECP/EPP in BIOS, the driver is unable to use any EPP mode (uses 8-bit and the oops is the same).
