it's really in there - please use jgarzik's netdev#upstream branch. Not sure
if it already made it to 2.16.17-rc5, but I don't think this made it into
2.16.17-rc4, so that is where you may be missing it.

e1000: Remove PM warning DPRINTKs breaking 2.4.x kernels
remove DPRINTKs that were printing warnings about power management on
2.4 kernels. Since we really don't react differently these printk
statements are not needed. This code was originally added to fix
some compile time warnings that got fixed by newer kernels.

DPRINTKs in e1000 code (2.6.x kernels)
Hello, I am wondering why this patch e1000: Remove PM warning DPRINTKs breaking 2.4.x kernels (http://www.mail-archive.com/netdev@vger.kernel.org/msg10803.html) was meant only for 2.4 kernels, and _not_ for 2.6 kernels. These DPRINTKs in e1000_suspend() are currently resulting in following messages while rebooting a system (2.6 kernel) which has e1000 adapter: Shutting down MD Raid done Stopping udevd: done proc umounted The system will be halted immediately. md: stopping all md devices. e1000: eth3: e1000_suspend: Error enabling D3 wake == e1000: eth3: e1000_suspend: Error enabling D3 cold wake == Power down. Should these DPRINTKs be removed from the 2.6.x e1000 code as well ?
