Hi,

Just booted -rc5 on another one of my boxes, and I get literally tons of
these everytime there's some network activity:

printk: 300 messages suppressed.
<NULL>: hw csum failure.

Call Trace: <IRQ> <ffffffff80357463>{__skb_checksum_complete+76}
       <ffffffff80381e89>{tcp_rcv_established+1384}

The box is using the sk98lin driver.
