Hello Toni,
I got an issue here. While copying files from an NFS share to a SCSI disk image the system is very unstable and I regularly get kernel panics. The suspicious thing: This only happens during network transfers and on 68040. It does not happen on 68030 with everything else being the same. Therefore I suspect a CPU issue. During networking NeXTstep makes heavy use of MOVES instructions, which is unique to networking. Probably this is the root cause of the issue. M68000PRM shows some differences for MOVES between 68030 and 68040.
Any idea what might be wrong here?
Best wishes,
Andreas
