Hi Brad,

Thanks to reply my email. I have tried to clean all connection on CPU but
these messages always scrolling. Beside them, there are another ones
"Warning processor level 4 interrupt not serviced" scrolling on the
console. Any relation these messages with the previous ones ("WARNING:
vme0:
Spurious VMEbus interrupt, level 4,vector 0xfa" ) ?
Thanks for your help.

Best Regards,
Millan R


In general, "spurious interrupt" indicates one of two problems:
blown/fused traces on a circuit board, causing the interrupt bit to go
high w/o valid origination
a race condition at boot, e.g., one or more resources taking longer than
expected to complete init/diags/init, or some device's timer is expiring
before it receives notification from one or more resources

Either way, the next step is to boot with full-on diags (OBP: set
diag-level max). Hopefully, you have a way to capture console output.

For either case, you'll almost certainly be replacing the mainboard,
unless the diagnostics indicate some other card/module/daughterboard. In
rare cases, dust or some other contaminant could be shorting one of your
mainboard's traces, so be sure to clean the inside of the case thoroughly
with compressed air (and possibly evaporating solvent).

Good luck, and be sure to summarize. This is one of those problems that
rarely shows up, and so is needed in the sun-managers archive.
