Hi,
Some more information: There is the same problem when I enable prefetch
instead of cycle exact. With one of these options enabled, the first time
when I start HDDRUTIL after resetting, parts of the data provided by
nf_scsidrv.c (in particular the device names) are incomplete.
Looks as if both options have something in common that causes this.
Best regards
Uwe
