I have NO problems with my internal ethernet port when I do this simple
procedure.  I am using RedHat 6.1, and kernel 2.2.14 with no patches.  The
eepro driver is compiled in to the kernel, not a module.

I edited /etc/apmd_proxy (which comes with the apmd distribution) to
shutdown the interface during a suspend and start the interface during a
resume.  Here is the patch:

My z505hs claims to have BIOS version 4.0, revision 6.0.  The eepro card
is assembly 100001-001 and its ROM checksum is 0x04f4518b.  If the above
procedure doesn't work for someone, I'd like to know what firmware
revisions you have.

Cheers,
