I was using pktgen to overwhelm the r8169 from a fast machine. Does 2.6.10 fail in a similar manner? eth0: Too much work at interrupt! eth0: Too much work at interrupt! ------------[ cut here ]------------ kernel BUG at net/core/skbuff.c:91! Any idea what this BUG actually means? Since it's in skb_over_panic(), a function designed to do nothing but BUG(), that doesn't tell us a whole lot about the callsite.
