Now it's working. Don't know why I wasn't thinking of this myself.
Thank you!
One thing to consider is that it could be a USB issue - could you copy the wallet to a hard disk or better internal flash drive?
If this is a slow USB device or older bus the process could be i/o bound which would be why CPU usage is so low.
It could be other things of course but this is a possibility.

Hello,
I am trying to access an old backup wallet and bitcoin-qt is stuck in rescan, it is taking forever.
I am using Ubuntu and bitcoin-core v0.9.2.1 with the blockchain and wallet on an usb hard-drive.
My debug.log:
I am confused because my CPU utilization is only at about 1% ...
I know that bitcoin-core does a rescan because of the old wallet but at this speed it will take forever.Is it rescanning all the blocks in the blockchain or just the last 318316 blocks?
Any ideas why this process is so slow (and my CPU only at 1%)?
Any help would be appreciated,

Edit:
Ok, I just realized that 318316 blocks is almost the complete blockchain at this point.
