Hello all,
I have recently installed OpenBSD 3.7-current (as of 07/12/05) and have
selected the bsd.mp kernel since I am running a system with 2 CPUs. After
looking at the dmesg output after the initial boot, I noticed the following
strange lines near the bottom:
ioapic0: pin 17 shares different IPL interrupts (40..90), degraded
performance
ioapic0: pin 18 shares different IPL interrupts (40..50), degraded
performance
ioapic0: pin 19 shares different IPL interrupts (40..50), degraded
performance
I have done google searches, but was unable to determine the cause of
these messages. Additionally, I have sought help on the #openbsd IRC channel
(freenode.net) but no one seems to be able to figure out what's going on
here. The details of my particular system are spelled out in the full dmesg
output, which is listed below.
Specifically, I would like to know what the reason for these messages
might be, whether or not they are anything I should worry about (the system
is up and running, with no noticeable problems thus far), and if there is
anything I can do to remedy the situation. As always, thanks in advance for
your help.
Cheers,
Mike
