Problem Description:

Depending on the kernel version writes are fast or slow on every kernel above
2.6.22 We have tested various driver versions, used utilities for firmware, but
still slow writes on latest kernels. We compiled and tested more than 20
kernels
We just discovered that after a quick test on new dell hardware poweredge m600.

Most of the current distrib are on 2.6.18, except Ubuntu and various vserver or
openvz kernels for debian. We tested redhat and suse too.




Steps to reproduce:

Very easy: We also check for an untar of the kernel (5x slower)
