Hi Stephen,

This looks like an issue I reported previously. After you use a recent skge, 
you can't use any older drivers or the windows driver, but skge still works 
fine every time.

The Gentoo bug report is here:

	http://bugs.gentoo.org/show_bug.cgi?id=100258

I closed the Gentoo bug as I hoped this patch would solve it:

http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff_plain;h=0eedf4ac5b536c7922263adf1b1d991d2e2397b9;hp=acdd80d514a08800380c9f92b1bf4d4c9e818125

But according to Steve Kieu, the problem is still there in 2.6.13. It's 
slightly odd as Steve was previously a sk98lin user and initially reported 
this problem for sk98lin in 2.6.13 whereas it did not happen with sk98lin in 
2.6.12.

Any ideas?

Thanks.

Tested , not broken, working now but the same problem,
that is if I reboot to winXP or 2.6.12, 2.6.11, the
NIC is unusaeble. In XP it always says link is down,
or media disconnected (from ipconfig command output in
XP)
is it because the firmware of NIC has changed or any
reason?


I noticed  warning messages only with 2.6.13 

PCI: Failed to allocate mem resource #10:2000000@0 for
0000:02:01.0

and modem device in 2.6.13 IRQ is disabled.

This is a different problem related to ACPI and other bus
changes in 2.6.13.

not sure if it gives more information.

Not sure how can I restore this thing back to normal
(sigh)

Is this the correct summary of the problem scenarios.
Assume each one starts from cold boot (power off).

* 2.6.13(skge) boot                    => Good
* 2.6.13(sk98lin) boot                 => Good
* 2.6.13 + SK version of sk98lin       => Good
* XP boot                              => Good

Okay, now the cases where one OS is run first and
a reboot is done to a second, or in the case of
just Linux, this should be the same as rmmoding on
driver and modprobing

	Second
First   | skge | sk98lin | XP
skge  	| OK   |  BAD    | BAD
sk98lin | ok   |  OK     | ok 
XP      | ok   |  ok     | OK
