Which model? There are several Thunder K8 Boards out there.
K8S, K8S Pro, K8W, etc. 

Furthermore: which BIOS Release?
I had trouble with all but the initial BIOS-Release for my
Thunder K8S (2880) Boards under i386-stable and i386-current
concerning interrupt routing issues (with and without ACPI).
I hope testing the various BIOS revisions under amd64-current
really soon.

Intel or Broadcom? The "intel" nics would be em(4), the Broadcom
nics would be bge(4). The Thunder K8S comes with dual bge(4).

You may try to downgrade your BIOS to V1.07.

Looks quite like an interrupt storm.

Do you mind showing the mptable output?

My boards where rock-stable with complete unconfigured nics; since
the culprit was a misrouted interrupt for the broadcoms. Sometimes
doing an ifconfig was sufficient to "halt" the machine, sometimes
I had to initiate a ftp transfer or other means to generate some
network traffic.
