fdomain SCSI driver broken in 2.6 series?

Hi everyone,
does anybody remember the state of the future domain driver in the 
current 2.6 kernel? I tried to find some pointers to the cause of an 
Oops I get every time during insmod with any 2.6 kernel, booting e.g. 
from two versions of the Gentoo installation CD and Knoppix, while the 
2.4 version of the driver detects the card and attached disk just fine. 
Even a self-made grub boot cd containing 2.6.11.10 and some userland as 
initramfs shows the same beahviour.

I am trying to get an ancient ISA adaptor to work, namely a Future 
Domain 1860 w/ 18C30 Chip, if I recall correctly. The card is detected 
properly at base 0x140, irq 11, and the scsi_eh_0 thread is launched as 
well. But even before the disk is detected, the problem occurs.

Unfortunately, I am currently away from the box in question, and did not 
manage to extract any further information so far. Any hints would be 
appreciated, and if I can provide some information that would actually 
be of any use, please let me know.

Thanks in advance,
Chris

I did a bit of cleanup on it during 2.5 to get it to compile and look
right, and it did work for a while when I had the card, but the scsi
changed a lot after that. You are the first fdomain user I've seen in
years so I suspect you are on your own for fixing it too tho I can try
and help a bit.

Guess I'm the only person insane enough to try and build a DSL router 
based on 2.6 with ancient SCSI disks on an ISA controller, but I just 
can't live without some of the features anymore which 2.4 still lacks.

In the meantime, I worked around the Oops by using a tiny disk on the 
onboard IDE controller, but I wouldn't quite call removing the card a 
fix for the problem.

The thing is, I have no real experience in C programming, although I 
sometimes read a little kernel source code and stuff. Right now I have a 
bit of trouble with my studies, but once that's settled I can do some 
reading about SCSI, Linux, the works. Doesn't seem to be anyone using 
2.6 with Future Domain cards anyway, so I'm not in a hurry. But just for 
completeness, it would be nice to have that driver cleaned up. It's in 
Linux' tree, after all. I'll build a testing box with ISA bus some time 
soon and try some debugging.

Thanks for your time : )
