Hmm.  The silence on this problem is, well, scary.  Maybe
nobody is actually working on UltraPenguin anymore?

I did find out that the machine in question is an Ultra-30, if
that helps.  Also, the message is apparently coming from Linux
itself:

/usr/src/linux-2.1.107/linux/arch/sparc64/mm/init.c:

...


#define MAX_TRANSLATIONS 64
static inline void inherit_prom_mappings(void)
{
        struct linux_prom_translation transl[MAX_TRANSLATIONS];
        pgd_t *pgdp;
        pmd_t *pmdp;
        pte_t *ptep;
        int node, n, i;

        node = prom_finddevice("/virtual-memory");
        if ((n = prom_getproperty(node, "translations", (char *) transl,
                                  sizeof(transl))) = -1) {
                prom_printf("Couldn't get translation property\n");
                prom_halt();
        }


I have no real experience with Ultra's, but if somebody could
give me the low down on what this code is trying to do, I could
investigate it further.
