ssh problem with kernel 2.6.32.10-90

[John]

Hi all,
This morning I updated my Fedora 12 64bit laptop to kernel 2.6.32.10-90. 
Immediately after I couldn't forward X apps over ssh anymore. Usually, I 
run X apps on my 3 laptops from my F12 64bit server. The server has been 
updated to kernel 2.6.32.10-90 at the same time. The 2 other laptops are 
running fine since they are running Fedora 13 alpha.
It is not a major problem since I went back on 2.6.32.9-70 on the F12 
laptop and everything is OK. I just thought that posting this might be 
useful for someone who has a similar problem.
If you have any idea on the cause of the problem, feel free to comment.
