I get the same thing. I have perfect behavior with the stock RedHat 7.2
kernel.

Hi!

My test is very simple. I have started X-Window and XMMS in order to
listen to some songs. Then, I have executed

dd if=/dev/hdc1 of=/dev/null

as root within a terminal, and I have got the following a few seconds
later:

The /dev/hdc1 partition capacity is 6 GB. My root partition is on
/dev/hda5. My computer is a Pentium III with 384 MB of RAM.

BTW, the same test in 2.4.6 works fine without any problem.

Regards.
