A customer reported a problem with the Unix "shutdown -r"
on his SMP sable machine.
Everytime he uses the "shutdown -r" command, the system
shuts down properly, but the system does't reboot automatically.
At the console the system just keep on printing
"IP interrupt CPU 0", halting it with the halt button
doesn't help, only the restart or power cycle cure
this...
we asked the customer to upgrade his system's FW to
v4.7 but this didn't help.
This is an EV4.5 (4/275) with 4 CPUs at the following revs:
Firmware : V4.7 (From CD v3.8)
CPU0 B2040-AB Rev B01 SW 34
CPU1 B2040-AB Rev B01 SW 37
CPU2 B2040-AB Rev B01 SW 37
CPU3 B2040-AB Rev B01 SW 37
Has it to do with the SW rev 34 of the 1st CPU (CPU0) ???
Feedback will be welcomed, the only idea I have left for
this is to replace the CPU 0 (rev SW 34), but we'll have
to plan the intervention outside normal working hours
(week-end probably) and I'd prefer to go straight to the
correct solution...
Cheers,

The message "IP interrupt on CPU 0" is printed by the console. The console
just dismisses the interrupt.
Suspecting broken hardware, from console mode, a deposit can be done
to cause an IP interrupt. You should see one message. If you see the
continuous stream of "IP interrupt on CPU 0" messages, then you have
broken hardware.
With an EV4

+-------- 0 or 1 or 2 or 3 to select which CPU
Sample log:
