[E1000-devel] recent e100 fixes cause kernel panic?

[Ed R. <er...@pa...>]

I'm using the Vyatta "kenwood" Linux distribution, which is currently
at 2.6.31-1.  I upgraded to their latest version, and began seeing kernel
panics shortly after starting to use ssh/scp on the network connected to
an e100 NIC.  I was able to reproduce the problem immediately after
booting up - sometimes it even crashed during the boot.

One of the crash logs is attached.

Since the problem seemed to be related to e100.c, I reverted the two
commits to e100.c that had taken place since I last built the kernel
for this box:

I rebuilt the kernel and it's not panicking anymore.
