Other problems have been report on other models that also use the ncr53c720
driver - most often filesystem corruption.
The problem has not yet been isolated - might be the driver code or the
hardware adapter code used with that scsi adapter.
In contrast, some pci add-in cards that use the driver are known to work(???).
Translation: Something is wrong, no one has yet offered a solution.
