These nice cards never worked good with Linux. It's based on old and ugly wd719x driver written back in 2.0 days, then hacked to 2.2 and finally to 2.4 kernels. Most of the code is rewritten: from ~4100 lines to ~1200. I've tested the driver on a WD7193 card with some hard drives and CD-ROMs: QUANTUM LP240S GM240S01X 4.6 IBM 0663L12 e g IBM DORS-32160 WA0A SONY CD-ROM CDU-55S 1.0t SONY CD-ROM CDU-415 1.1g The card supports TCQ and linked commands (for cmd_per_lun > 1?) but I don't know how it should be implemented in a driver. Device/bus/host resets seem to work fine when tested by sg_reset. But don't know how to test command abort. The card requires firmware that can be cut out of the Windows NT driver that can be downloaded from WD at: http://support.wdc.com/product/download.asp?groupid=801&sid=27&lang=en There is no license anywhere in the file or on the page - so I guess that the firmware cannot be added to linux-firmware.
