Replying to [comment:1 kallisti5]:
> 10134778 unhandled apic_timer_interrupt int's as per kdl. I'm guessing
that is part of the problem... trying machine with apic disabled.
As explained in IRC the APIC timer is part of the local APIC, not of the
IO-APIC so this doesn't corelate. An unhandled count roughly the same as
the hamdled count is expected and unproblematic.
Disabling the IO-APIC means the interrupt routing is pretty much fully
different. Please attach a syslog of a boot with IO-APIC enabled, from
that the intrrrupt routing can be deduced for both cases.
Generally the IO-APIC allows for more interrupt vectors to be used so it
usually reduces interrupt sharing. It is still up to the system
implementor to wire things up though, so in your case there might be
shared interrupts in that case.
I think the rtl driver supports MSIs as well, so the routing may be moot.
Again a syslog would tell.
