So yet another week, another -rc. This one should be the last one: we're 
certainly not running out of regressions, but at the same time, at some 
point I just have to pick some point, and on the whole the regressions 
don't look _too_ scary. And -rc8 obviously does fix more of them.

Most of the changes since -rc7 are pretty small, and there aren't even a 
whole lot of them. The shortlog (appended) is just a couple of pages, and 
the diffstat is even smaller, but since the dirstat is a dense overview, 
I'll just put that here instead:

   4.6% arch/m32r/kernel/
   5.7% arch/m32r/
   9.5% arch/mips/pci/
  10.4% arch/mips/
   4.2% arch/x86/kernel/
   4.4% arch/x86/
  26.0% arch/
   3.5% drivers/usb/storage/
  10.4% drivers/usb/
   3.6% drivers/watchdog/
  23.8% drivers/
  11.5% fs/xfs/
  13.5% fs/
   3.7% kernel/
   9.8% net/9p/
  10.6% net/
   5.4% scripts/kconfig/
   5.9% scripts/
   7.4% sound/soc/codecs/
   8.4% sound/soc/
  10.1% sound/

and it's actually more spread out than usual. Arch and drivers are just 
half of the patch even when combined. 

Give it a try,

If 2.6.27 is released with e1000e driver corrupting EEPROM contents on 
many systems out there, rendering the cards unusable for most of the 
i-am-not-a-hacker users (and remember, even Dave Airlie bricked his laptop 
completely to death, when trying to restore eeprom contents), well, I 
personally find that very scary.

Intel is working with us on tracking down and resolving the issue, but 
this is not going as well as one would like to see (one attempt, one card 
with completely hosed EEPROM contents ... and restoring the contents is 
not *that* trivial).

Intel has some patches to mitigate the symptoms (even though we still 
don't know who is causing the breakage, but Xorg is the biggest suspect in 
my eyes), but they are neither in your tree nor in any other maintainer's 
queue yet, as far as I know.

What's the magic to trigger it? I've got a laptop with that e1000e chip in 
it, and am obviously running a recent kernel on it. Do people have a 
handle on it? Is it actually verified to be kernel-related, and not 
related to the X server etc?

If we had the magic we'd have fixed it by now, the current working
theory is its X server related. This
hasn't been proven, though my ATI GPU e1000e seems fine so it may have
some legs.

If it is X related then its both a kernel + X server issue, the e1000e
driver opens the barn door, the X server drives the horses through it.

Of course until someone produces a way to fix the hw after it breaks,
reproducing this isn't something for the feint hearted. I'm hoping my
laptop
comes back today with a brand new motherboard in it.

Dave.

Are you sure? There was a mandriva report abou NVM corruption on an e100 
too (that one apparently just caused PXE failure, the networking worked 
fine).

So I wonder if it's _purely_ X-server-related, adn the reason people blame 
2.6.27-rc1 is just timing of some X update and then people just look at 
the kernel beceuse the 'network card failed' looks so kernel-related.

The reason I mention that is right now it looks like the distros are just 
running around disabling the e1000e module, or perhaps downgrading it. 
Which may not even work!

The discussions in some of the bug-trackers seem to be full of people who 
have no actual information, but are perfectly willing to flail around 
wildly saying obviously crazy things.

The Ubuntu people are some of the crazier ones (should I be surprised?), 
but that one also has Ben Collins claiming they use the same e1000e driver 
for the 2.6.26/27 kernels (from intels sf.net project). That may be bogus, 
but if true it would indicate that it's possibly not so kernel-related, or 
at least not so e1000e-driver-related.

we have a patch to save/restore now, in final testing stages
(obviously we want to be really careful with this)

Note that so far it seems to mostly hit with "new" distros, so both
new kernel and new X... ;(

Btw, the _real_ bug is clearly in the hardware design that allows you to 
brick those things without apparently even having a lock bit.

I'm hoping Intel doesn't treat this as just a software bug. Some hw 
designer should be thinking hard about which orifice they put their head 
up in.

It used to be that you could fry some monitors by feeding them 
out-of-range signals. The _monitors_ got fixed.

Mostly. I think you can still do bad things to internal LCD's on at least 
some laptops. Although I hope I'm wrong.

You still can in some cases. You can also erase many video card
firmwares, trash disks, brick DVD drives and the like fairly easily too
but you do tend to have to try to be evil in these cases, not just get an
address wrong.
