Subject: Sun4d SMP wierdness
Date: Sun, 15 Aug 2004 00:57:12 +0000 [thread overview]
Message-ID: <200408150157.12181.crn@netunix.com> (raw)
I am trying to track down why 2.4.27 (or any 2.4 series) does a watchdog
timeout very early in the boot sequence om Sun4d SMP.
In arch/sparc/kernel/setup.c I put some prom_printfs to narrow it down.
setup.c line 450
prom_printf("tp6\n");
paging_init();
prom_printf("tp7\n");
tp6 gets printed at boot, tp7 does not.
So - in arch/sparc/mm/init.c line 328 I add another test point
void __init paging_init(void)
{
prom_printf("mm/init.c:paging_init %d", sparc_cpu_model);
switch(sparc_cpu_model) {
OUCH - this never gets printed so somewhere the function call to paging_init
is vanishing into lala-land.
At this point I am stumped - What could be happening ?
