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.
