Either that or file system errors. Does fsck run ok or does it say anything unusual? There are several theoretical reasons for such errors that are connected with the fact you use solid state drives, but all are tricky to diagnose if you don't have a certain repeatable test you can try. For example: some SSDs optimize writes to "spread out" the IO on the chips, but some do it by looking into file system structures to determine where it's safe to relocate the write - obviously this works only with a known and supported file system. This is a really wild guess, but maybe the SSD firmware has error somewhere in this area, trying to interpret UFS as it was FAT? If you manage to get a repeatable failure test, you can try formatting the drive as FAT32 and trying it on that. Or maybe it's just a bad drive... > The system-disk is a RAID1 on an ICP 5805.
