It is visible with: vmstat -m | grep "ATA r". Looping this every minute shows the kernel memory usage increasing at the rate of over 2 MB/minute. This means all available kernel VM is exhausted after about 1 hour of access. # vmstat -m | grep "ATA r" && sleep 60 && vmstat -m | grep "ATA r" ATA request312010 39002K 39002K 316526 128 ATA request330424 41303K 41303K 334980 128 >How-To-Repeat: Using ATAPI/CAM, use mplayer to play a DVD.
