Re: e1000e NVM corruption issue status

this is the current set of patches that I have to help us debug
and/or fix e1000e issues found during this debug effort for
the corrupt NVM.  the "drop stats lock" - "reset swflag" patches allow 
Thomas' patch for a mutex in the SWFLAG acquire function to run without 
any errors.

the patches are not probably production quality, but seem to work
for myself and thomas on at least a couple of machines.

The non-debug aspects of the patches will likely be pushed later.

At this point I do not believe any of these patches will fix the
NVM corruption issue, but will add to the ability of any tester
to help find the issue, and reduce the chance that it is any issue we 
(now) know about.
