Can you test the new skge driver instead? If that one is broken then we 
probably have more chance of getting it fixed :)

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.

	http://marc.theaimsgroup.com/?l=linux-netdev&m=112268414417743&w=2

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.

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

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

on 2.6.11/12 when it isn't working maybe you should send us the output
of lspci -vvv

just a hint, I'm guessing its power management related, and / or
something to do with the pci bus code.

Also, the dmesg output with skge driver will show chip version and revision.
The problem is obviously some of the chip initialization that is complex
with the Marvell chips. Something is probably missing.  There was a fix
in the latest 2.6.13 that is probably related:

Re: Very strange Marvell/Yukon Gigabit NIC networking problems

[Stephen Hemminger]

You have a version of the Marvell Yukon that was affected
by a fix in 2.6.13.
	skge addr 0xfeaf8000 irq 19 chip Yukon-Lite rev 9

Both the skge and sk98lin driver were fixed to check for this.
Without the fix, the chip will be in the wrong power mode.

The version of sk98lin driver from SysKonnect already had the
fix, so if your distro used that one, it would have the reset
the power mode as needed.

I am afraid not. The last time, I reproduced the
problem using the latest sk98lin driver from
SysKonnect  (run create patch and patch the kernel
2.6.13). Problem still there. The file I got from
sysconnect is:

install-8_23.tar.bz2

Just look for references to CHIP_REV_YU_LITE_A3 in the driver
	sk98lin/skgeinit.c and sk98lin/skxmac2.c
The comparison should always be:
	pAC->GIni.GIChipRev >= CHIP_REV_YU_LITE_A3
otherwise it will not correctly take chip out of powerdown (coma) mode.

please send me a patch to the install-8_23.tar.bz2
then I can test. Or intruct more details, which line
and what should change then I can do manually.

I have nerver done device driver programming in my
life!

So, am I right in saying we can't do anything in skge to work around this to 
allow those older buggy drivers to work on the next reboot? More reports are 
cropping up, e.g.:

	http://forums.gentoo.org/viewtopic-t-375828.html

Given that it seems to be affecting the Windows drivers too, it would be great 
if something could be done.

Thanks,
Daniel

Stephen recently posted a patch which looks like it might solve this issue.

Steve, maybe you could test it out? I have attached it to this Gentoo bug:

Have tested it and it does *not* solve the problem for
me.

Besides lots of other problem with 2.6.13 for me, like
modem device not work, lots of extra modules not
compiled  (ov511 ; unionfs etc..) so even it works I
still need to revet back to 2.6.12.
