FreeBSD frankenmobl 5.2-CURRENT FreeBSD 5.2-CURRENT #5; Mon Feb 2 10:24:30 PST 2003 root at frankenmobl:/usr/obj/usr/src/sys/CURRENT i386
>Description:
      After suspend resume on IBM T40 2373JU5, em0 reports;
em0: The EEPROM Checksum is Not Valid
em0: Unable to initialize the hardware

Tried a few reported "fixes" from various websites, none resolve the issue.

Works normally prior to suspend/resume.
