Test server hang while running rhr
(network) test on RHEL4 with kernel
2.6.12-rc1-mm4
Could you tell me what the rhr test is? Is this an IBM internal test tool?

Might be a bug in the e100 driver, might not be.
I assume this is the
BUG_ON(skb->list != NULL);
in __kfree_skb(), although the line number is off-by-one, and the
.__kfree_skb+0x188/0x240 would tend to contradict that. Anton, can you
help work out where we went splat please?
tx timeouts are fairly rare events, so this might not be a recently-added
bug.
Do we know if it is repeatable?
