This is the test I've done: boot the system with 2.6.28 (config is copied from 
2.6.27 which works ok); from another system attempt to scp a 45MB file to 
this system; the scp stalls (and finally fails) at around 60%. This is 100% 
reproducible in this way. Attached is the full dmesg output and the config.

The output of 'free' during all this:
             total       used       free     shared    buffers     cached
Mem:       3083944     114304    2969640          0       4160      61096
-/+ buffers/cache:      49048    3034896
Swap:      2104472          0    2104472
