Does this patch help?

net: Fix frag_list handling in skb_seq_read

The frag_list handling was broken ini skb_seq_read:

1) We didn't add the stepped offset when looking at the head
are of fragments other than the first.

2) The frag index wasn't reset.

This patch fixes both issues.

Without the patch I do not get the oops Jesse saw. The iscsi driver logs 
in and I do not see a problem until running IO (scsi read commands). The 
iscsi code thinks there is a missing packet at the iscsi level and 
begins recovery at that level.

With the patch running against linus's git tree, my box locks up. You 
cannot ping it. I do not get a oops or anything in the logs, and the 
keyboard does not respond. I will try to get some oops output and more 
info.

I am not able to get anything. Box is gone.

Jesse, without the patch you guys were getting an oops trace right? Did 
you get one with Herbert's patch?
