Note that I still see this in current Fedora 9 kernels.
Comment 3 Jesse Brandeburg 2009-02-09 17:06:11 EST
can you please check to make sure you are seeing interrupts on your interface after resume

is there a chance you could run the ethregs utility before and after resume?  I guess you'll have to build it, you'll need the pciutils-devel rpm


also the output of ethtool ethX after resume, and ethtool -S ethX

I gave up on hibernate for a while, but tried it again this morning and cannot reproduce.  

I presume somehow this has been fixed in the kernel.

Feel free to close with the appropriate status.

I'll reopen this if it ever re-appears.
