Postfix problem on 2.4.21-ac2

[Thijs Welman <thijs@balpol.tudelft.nl>]

Hi,

I upgraded the kernels on some of my servers running Debian Woody, 
yesterday to 2.4.21-ac2 (compiled from source), or at least i tried to.

Using the 2.4.21 kernel with Alan Cox' ac2-patch, all messages i send 
through Postfix get corrupted:

[mail.log]
Jun 24 06:27:46 aranea postfix/qmgr[399]: warning: 
active/0/4/04E5B17E3F: too many length bits, record type 255
Jun 24 06:27:46 aranea postfix/qmgr[399]: warning: 04E5B17E3F: envelope 
records out of order
Jun 24 06:27:46 aranea postfix/qmgr[399]: warning: saving corrupt file 
"04E5B17E3F" from queue "active" to queue
"corrupt"

Rest of the applications seem to work fine; no other strange logentries 
or messages...

This problem only occurs with the 2.4.21-ac2 kernel. The 2.4.21-vanilla 
and 2.4.21-ac1 kernel are fine. I'm not sure if it's a problem in de ac2 
patch itself (couldn't find anything on the kernel mailinglist, etc) or 
the way this Postfix version runs on this specific kernel...

I was wondering if anyone has the same problem, or maybe some other 
similar problem with the 2.4.21-ac2 kernel.

thanks,
