** Description changed: My system have been behaving really slow, and after some investigation, I've traced it to some sort of IO-problem. After changing FS to XFS, - I've discovered that the source of the problem really seems to lie on + I've discovered that the source of the problem really seems to lie one level deeper, directly at IO. After buying a new drive, this time SATA, and with a brand new SATA controller. (Promise SATA 300 TX4). That haven't helped at all. In a standard session, opening a terminal and typing hdparm -t /dev/sda gives me around 18MB/s. If I reboot and pass init=/bin/bash, the same hdparm test gives me ~40 MB/s. Again, reboot, and hdparm from tty1 before logging in, around 25MB/s. Killing acpid, up to 40-50MB/s again. Logging in, back down to ~20. Starting glxgears (??!?!?), and hdparm gives me again ~50MB/s. Any clues on how to find exactly what is eating my harddrive, and why?
