e1000e bug - 32 bit, 64 bit or Both?

[Chuck Forsberg WA7KGX]

Has this corruption appeared on both 32 and 64 bit Linux flavors,
or just one?

There's one driver for both platforms so I suspect it will happen on
both 32 or 64 flavours.

AFAIK reasons for the problem are still unknown but reports of
corruption presumably come so far from 64-bit machines.  It appears
that some race is involved so it may be that its window is easier to
hit with 64 bits?

64-bit hardware, certainly - presumably almost any hardware that
has the effected Ethernet card(s) would be a Core 2 or better 64-bit
machine.

But I'm fairly sure (it's been about a month, so I could be
mis-remembering) I've only tried installing 32-bit versions of Fedora
and Ubuntu - and my Ethernet card was affected.

I'm running 64-bit Linux (Fedora, C5, opensuse 11.0) on relevant 
hardware. I will _not_ try the opensuse beta (the docs suggest 
destruction is possible), and if I keep updating Fedora 10 alpha I 
suspect I will lose the Internet.

I tried F10 beta, and my ethernet card doesn't work because they 
disabled the e1000e driver.  At least it didn't fry my NVRAM.

I wonder what kind of help I can provide seeing as I have the affected 
hardware, but without actually ruining my card.

According to a comment in a koji update to the kernel today, the problem
has been fixed. I haven't yet seen that announcement anywhere out.
(Note this is supposed to be a real fix, not the work around previously
implemented to disable the driver.)

Good catch! Here's the comment [1]

Apparently, upstream's fix was so fast this bug never made it past
NEW. Now what? [2]
