Adaptec 2100S and 2.4.7-pre8(and 2.4.6-ac5) i2o driver

[Ole Gjerde]

Hi,
I've been trying to get this Adaptec 2100S RAID card to work.  It works fine
with the adaptec patch(the dpt_i2o driver), but I would really like to get
it to work with the stock i2o driver.  According to the messages I've seen
so far this should work without any problems.

However, when the kernel boots, it scans the bus, finds the card and starts
the initializing and then it oopses.

Kernel: 2.4.7-pre8 and 2.4.6-ac5

Hardware:
Intel STL2 MB
Dual P3 1GHz
512 MB ram
Adaptec 2100S in a RAID5 (~36G)
network: eepro100 on MB and 3com 3c905B

All drivers builtin(modules disabled).  And all partition + swap on the RAID
device.

Last message on console before oops:
i2o_scsi: Attempting to reset the bus.

Here is the ksymoops'ed oops(NOTE: This was hand copied, but I think it's
right :)  (oops is from 2.4.7-pre8):
