I have attached two files. The dmesg/out and a file with the trace.

I have also tried the 4 megabyte kernel. Sometimes things never work as you
expect. It now seems that the code for accessing Acorn SCSI card is enabled.
This is now desrupting the startup of the kernel. I have attached the
dmesg/out file (named dmesg/asc) for you to examine. I almost don't dare to
ask you but could you build a 4M kernel without the Acorn SCSI card? You
are still waiting for the new asc driver in the arm32 tree?
