Hi Daniel,
In this case, it is not a SIMM module issue (I have replaced them all
some tome ago in order to get more memory as 16M was a bit small).
The SunOS4.1.1 kernel does not have this problem. It must reset somthing
early on in boot that prevents the issue from occouring.
Regards
Mark Fortescue.

Hi,
On my sun4c OPUSstation (Sparc 1 clone) I regularly get tripped back to the
Prom during boot:
...
ok boot vmlinuz -p
Booting from: sd(0,0,0)vmlinuz -p
root on sd0a fstype 4.2
Size: 2675008+0+142756 bytes
Booting Linux...
Watchdog reset
Window Underflow
ok
I have the similar problem on SS5 and remove a put back SIMM modules solve
this problem.

The boot prom is Revision 1.0. Is there a way of doing a full Prom reset as
part of the boot sequence to try and remove this issue.
If I redo the boot or do a powerup reset boot, there is no issue at this
point.
