oops: 2.2.15pre10 + eepro100 v1.09j-t [long]

	Greetings, all.  I have a Compaq Proliant 3000 (two-way PIII 500MHz)
with one NC3120 (Speedo3) NIC.  Kernels up to 2.2.14 run perfectly.  Kernel
2.2.15pre10 (also pre7) oops'es when I manipulate the eepro100 driver.

	I am suspicious about the PCI resources -- when using the 2.2.15pre
kernels, the base I/O address for the NIC looks all wrong.  ifconfig picks
up on this, and reports a bogus I/O address -- perhaps a resource conflict?

	First, here's the output from ksymoops.  This happens each time that
I unload the eepro100 module, and then attempt to cat /proc/ioports.  If I
reload the module, snooping around /proc does not result in an oops.

-----------------------

	Here's what my /proc/ioports looks like with the eepro100 module. 
With other (non-pre) kernels, the NIC shows up correctly at 0x4800:

-----------------------

0000-001f : dma1
0020-003f : pic1
0040-005f : timer
0060-006f : keyboard
0080-008f : dma page reg
00a0-00bf : pic2
00c0-00df : dma2
00f0-00ff : fpu

03c0-03df : vga+
03f8-03ff : serial(auto)
e08a4000-e08a401f : Intel Speedo3 Ethernet
	
-----------------------

	Here's what ifconfig makes of all of this. Note the base address. 
There's a SCSI host at 0x4000; could this be part of the problem?

-----------------------

-----------------------

	Here are relevant entries in /proc/pci:

	Finally, here's my kernel message buffer leading up to the oops:

	Pleae let me know if you would like to see my kernel .config file,
or any other information.  Thank you in advance for your assistance.
