Hi all,
I get continuous reboots on my guest system, including these dmesg entries:
[ 31.770538] device tap0 entered promiscuous mode
[ 31.770554] br0: port 2(tap0) entering learning state
[ 39.259921] kvm: 1517: cpu0 unhandled wrmsr: 0x0 data 4000000080532d74

[ 50.481469] kvm: 1517: cpu0 unhandled wrmsr: 0x0 data 4000000080532d74
[ 50.481583] kvm: 1517: cpu0 unhandled wrmsr: 0x0 data 0
[ 50.481685] kvm: 1517: cpu0 unhandled wrmsr: 0x0 data 0
[ 55.827950] br0: port 2(tap0) entering disabled state
[ 55.828110] device tap0 left promiscuous mode
[ 55.828200] br0: port 2(tap0) entering disabled state
My ./configure is:
./configure --prefix= --target-list=x86_64-softmmu --disable-vnc-png
--disable-vnc-jpeg --disable-vnc-tls --disable-vnc-sasl --audio-card-list=
--audio-drv-list= --enable-sdl --disable-xen --disable-brlapi
--disable-bluez --disable-nptl --disable-curl --disable-guest-agent
--disable-guest-base --disable-werror --disable-attr
My qemu cmdline is:
/usr/X11R6/bin/qemu-system-x86_64 -serial /dev/ttyS2 -readconfig
/etc/ich9-ehci-uhci.cfg -device usb-host,bus=ehci.0 -device usb-tablet
-drive file=/dev/sda2,cache=off -m 1536 -net nic -net
tap,script=/etc/qemu-ifup -no-acpi -monitor stdio -L /usr/X11R6/share/qemu
-boot c -localtime -enable-kvm
Was fine with qemu-kvm-1.0 and the same options!
Best regards,
Erik

Erik,
Can you bisect to find the culprit, please?

I will try to do that. Currently I have to find another issue between
0.15.0 and 1.0 :-) After having found that, I will continue bisecting here :-)
Best regards,
Erik
