We need to run some legacy hardware that requires a 16-bit Fsys (to run
with a special modification of Fsys.aha7scsi). We run this on a 32-bit
system (4.25) along with a regular 32-bit Fsys by using spatch to change
the registered name of Fsys and the name looked for in Fsys.aha7scsi.
This has been working in the field just fine for a long time
Recently, we had to upgrade the processor to handle some new features
and are now having problems with a faster processor (850MHz instead of
233MHz.) The problem is a hang in the 16-bit Fsys during an open of a
scsi device.
The 16-bit Fsys is version 4.21M. Is there a later 16-bin Fsys?
