New ASUS 1701 bios for M2N SLI DELUXE

[Gene Heskett <gene.heskett@gmail.com>]

Hi Robin, David and lkml list;

I said I would report.

I just reinstalled the 1502 version bios after spending the last 2 days 
trying to get an hours worth of uptime without an oops.  Gave up.

David Newell and I have been trying to find the cause of the oops, but 
when the compile instructions David is sending me don't work, its a bit 
difficult to troubleshoot beyond renaming the function just to see if 
the oops follows the rename, which it does.  And with the boot girations
to get a working radeonhd driver now broken again, apparently by the 
'make mrproper' that David had me do, I'm now stuck on issue drivers for 
drm, radeon, and radeonhd and those are noticably slower.

So I'm back on the 1502 version of the bios, it does an oops as I sent 
before right at entering vmlinuz, which marks me tainted, but the machine 
is dead stable after that.

Here is another snip of that to refresh memories:

So based on that, I'll now go build a 2.6.29-rc8 and see how that runs.

The biggest problem with the 2.6.29 series is that apparently, for security 
reasons, they are now doing a PHY disable in a graceful shutdown, which 
none of the previous kernels knows how to re-enable.

So to reboot to the 2.6.28.7 stable, you have to use the front panel reset 
button to reboot or you will not have any onboard ethernet until you do a 
full, pull ALL the power plugs for at least 30 seconds (I go make a cup of 
tea, about 3 minutes) to reset the PHY's back to operational status. TBT,
the reset button is easier.

Frankly, that seems like a thoroughly busted security idea, but I suppose 
we're stuck with it.

It also seems to me, that to mark my kernel as tainted over a fix-up that 
makes the system dead stable, is executing the messenger.  IMNSHO, its ASUS 
who ought to be shot for not having any method of filing a bug report 
against their crappy bios.  3 emails sent to the only address I was able to 
find for ASUS have had the same effect as sending them to /dev/null.

If anyone on the LKML knows how to contact ASUS, please advise them that 
there is at least one VERY unhappy camper/user of the 
$285 USD M2N SLI DELUXE motherboard, I'm sorry I ever laid eyes on it. 
The newly released version 1701 bios (it unzips as M2N-SLI-Deluxe-1701.BIN) 
still doesn't get it right AFAIAC.  The kernel writers at least know what
to do about the older version bios.  Maybe ASUS coded the new bios to get
past your test, but is it still fscked?  That is certainly my opinion...

Thanks everybody.  Now back to your regularly scheduled programming. :)
