Hi experts,
I'm using freebsd sincs years, and have never seen such a suspicious =
problem, detail see below:
Any ideas, it seems it's an board induced problem .....
Probloem:
I can access the tape (also a CD-RW Writer) on the SCSI bus and write =
data (tar) without any errors or kernel messages to and from the tape.
When I read the data back I get random changed data in the files!
Repeating the procedure gives differences in different files at =
different positions. The Problem occured first when changing to the =
new ASUS board. With a P2B before all worked like a charm.

Checked:
Changed the SCSI controller (worked well in another board)
Tape and CD-Writer are o.k. at another board.
Changed SCSI cable
Changed slot fot SCSI adapter, now it has it's own interrunpt
Hardware:
Asus CUV4X with 933 MHz PIII
256 MB
IDE Disk
Adaptex 2940
HP DDS1 Tape Drive
