"checksum error" for 3C905C ....

[Kedar Swadi]

Hi,
   I have installed Redhat Linux 6.0 on a Pentium III (Dell Dimension XPS T450).
   It has the 3Com 905C (Tornado) network card. While rebooting the machine
	after installing the new driver I get a "invalid checksum 00c8" error .
	As a result I cannot access the network.

	The diagnostic tool gives the output given below. 

	Is there any patch that could help?

	Thanks in advance.
