Can it be related to this issue somehow?

It was tested on FreeBSD 8 and high UDP traffic on igb interfaces emits
messages "GET BUF: dmamap load failure - 12" and later results in kernel
panic.
We have not received any response to this report.
Could be the issue, however in our case there is no panic, just that all
userland activity in the system ceases for 2 minutes after it reaches
certain network load level.
