Ahoy. I've been using the patch for a while, and, recently, when the 
load on the wireless network I needed it for has increased, I've started 
getting kernel panics that I think the patch is responsible for. The 
panics are usually foreshadowed by messages in the style of "Sep  3 
11:34:14 unique kernel: delayed m_pullup, m->len: 22  off: 38333  p: 97" 
in the kernel buffer. I like to think that I've eliminated the 
possibility of bad hardware by changing the motherboard, memory, and 
Ethernet controllers in the machine, and have tried both Eugene's 
original patchset and the one that was committed to 7-STABLE, with the 
same ill effects. Any ideas about what might be wrong, or shall I set 
about getting a backtrace? Thanks.
