In-Reply-To: <456D7F4B.1000307-atKUWr5tajBWk0Htik3J/w@public.gmane.org> (Avi Kivity's message of "Wed, 29 Nov 2006 14:38:35 +0200")

I still see the

rtc: lost some interrupts at 1024Hz.

message with your patch applied.

One thing I noticed is that my serial console seems to be related to
the messages.  I just booted my machine with the serial console
printing kernel messages, and I saw the lost interrupt messages when
starting a guest twice in a row.  Then I did

    echo 0 0 > /proc/sys/kernel/printk

and started a guest with no lost interrupt messages.  And then I did

    echo 8 8 > /proc/sys/kernel/printk

and the messages started spewing out and my machine was hosed to the
point where I couldn't kill the guest again.

The only message that actually printed on the serial console before
the machine got stuck spewing rtc messages was

device tap0 entered promiscuous mode

(I'm using tun and bridging for my qemu networking)
