I think the bug you are seeing is due to the inline definition for
xchg in asm/system.h. The problem occurs in exchanges with 0 when
the address used in the ldcws instruction is not aligned on a 16 byte
boundary. Change the define for xchg to just use the spinlock method
in all cases.
The other option is to align all the addresses that are used in xchg's
with 0.

Hi,
I have also just tested it on a 887/G50 and a 827S, both from scratch SCSI
disks. Everything went perfectly.
Well done
