You need to decode those oops symbols before you can get a real picture of what is happening here. Oh, and 2.6.13 is about 2 1/2 years old, you might want to use a newer kernel version, trying to use a newer version of udev with such an old kernel version is not supported by anyone and you will be very lucky if it works at all. good luck, greg k-h ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
