Comment 9 Chris Snook 2006-05-24 21:12:05 UTC
I have a customer on RHEL 3 U7 experiencing hangs under TCP load with many
threads trying to kfree_skb.  Not sure if it's the same or not, but it needs
looking into.  I'll probably be escalating an IT shortly.

Comment 13 Jason Baron 2006-06-23 18:17:40 UTC
committed in stream U4 build 39.2. A test kernel with this patch is available
from http://people.redhat.com/~jbaron/rhel4/


Comment 16 Mike Gahagan 2006-07-13 17:11:04 UTC
ok, the patch is definately in 40.1.EL and it looks like IBM has hit an entirely
different problem which I don't think they have mirrored to us.

I'm marking this as verified, but IBM needs to open a new IT/bug to address the
new crash they have found.
