Segmentation Fault when accessing partition

Wed Feb 23 11:32:45 UTC 2005

Hej All

I'm having a similar problem. I can read the root level of my vfat windows 2k partition and some directories below, using ls. However if I try to read the 'winnt' directory I first get a segmentation error and if I try again ls hangs.

What might be important is that the Win2k is a Japanese version.

The same thing happens if I try to use a usb-memory containing Japanese files names. On the other hand I have not experienced any problem with my usb hard drive (unfortunately I don't have it here right now)

I'm using custom kernel 2.6.10 (FC3 configuration + nsp32 scsi-driver)

'fdisk -l ' with the usb-memory pluged in gives
