7193 and driver

Hi!

I've got a WD 7193RTL PCI card and Linux-2.2.9. I downloaded the
patch for Linux-2.1.54 (and changed it to match) and the latest
driver (1998/03/29). I had to change some things in the driver
to make it compile/work in Linux-2.2.9.

See below for more information about my system.

Okay, my card is detected as 7193 after I changed the code to
recognize the device id "0x3296" instead of 0x3197 as WD
cards. In fact, my /proc/pci (yes, it is obsolete) says:

  Bus  0, device   3, function  0:
    SCSI storage controller: Western Digital Unknown device (rev 0).
      Vendor id=101c. Device id=3296.
      Medium devsel.  IRQ 9.  Master Capable.  Latency=64.  Min Gnt=5.Max Lat=6.
      I/O at 0xec00 [0xec01].
      Non-prefetchable 32 bit memory at 0xebfeff00 [0xebfeff00].

My problem now is that I get a "WCS checksum error" because the
card returns a 0x00 data status ("no interrupt pending") instead
of a 0x01 ("ok") after the ENABLE_ADVANCE_MODE command. And the
Linux interrupt counter in /proc also says that IRQ 9 has never
been triggered (maybe I'm confusing something with internal
Spider interrupts here?).

Removing the check of the return code results in a frozen Linux.

Also, I added the "Error code:" debug output.

Here are the logs so far:

Hope that helps. Are there any yet unpublished code changes? And:
Where can I download a copy of this mailinglist's archive?

Note that the "9" entry appeared after the first load of the driver.
The "name" field consisted of bogus text. I think I'll have to fix
that and update the driver to the 2.2.x API.
