I just upgraded one of our Sun-3/280 fileservers from SunOS 4.0.1 to 4.0.3, and have run into the following when I boot from the new kernel: SunOS Release 4.0.3 (GENERIC) #1: Fri Mar 16 19:41:38 EST 1990 Copyright (c) 1989 by Sun Microsystems, Inc. mem = 8192K (0x800000) avail mem = 7168000 Ethernet address = 8:0:20:0:76:13 xyc0 at vme16d16 0xee40 vec 0x48 xy0 at xyc0 slave 0 xy0: <Fujitsu-M2361 Eagle cyl 840 alt 2 hd 20 sec 67> si0 at vme24d16 0x200000 vec 0x40 st0 at si0 slave 32 zs0 at obio 0x20000 pri 3 : : (a whole bunch of lines with just a single colon) : Watchdog Reset! ... after which the kernel halts. The watchdog reset message occurs just as autoconf is about to print ie0 at obio 0xc0000 pri 3 but it never gets this far (ie0 is the last device to be recognized). This occurs for the generic kernel supplied on the distribution tape, a generic kernel that I made myself, and a custom kernel ... The old 4.0.1 kernel works fine (I am using it now until I can resolve this), and the 4.0.3 kernels work fine on diskless Sun-3/60's (these have le0 in place of ie0). Has anybody seen this before? Is the ie0 driver broken? If so, is there a fix?

I have seen this watchdog reset peculiarity on my Sun-3, and I made it go away by unplugging the ethernet cable. It only happened when the boot device was a Xylogic Disk. I'm not sure, but I may have cured the problem by clearing the autoboot addresses in the EEPROM. For good measure, make everything from address 17 to address 1e 0.
