This is what my kernel says for both of onboard network cards. What does it mean? Should i be worried? My network cards have already hanged in recent past and required software reboot.

Here is some more info about my system:

[eccerr0r]

I'm using a single channel sky2 Gbit ether, and it seems to be stable on 2.6.21... The error messages (are the oops?) look like they should be forwarded to the linux kernel mailing list or the driver maintainer directly, seems multiple instantiation of the driver is potentially messed up. Is there a complete error log, cross referenced with symbols (the ffffffff8034ccbd doesn't mean much without the symbol table).
