Yes, I fixed the SCSI problems for 2.4. However, there were also some second-order issues in the file/block-subsystems. I probably don't remember all the details, but one example is that the disk block-size used to be stored in a 16 bit variable. Not so good if your block-size is 64KB. ;-) That one definitely has been fixed. But I wouldn't blindly trust that the 64KB page size is fully working, even if there are currently no known problems. --david
