Description of problem:
after starting and running Fedora from kernel kernel-2.6.27-0.337.rc6.git5.fc10.x86_64 and starting a kvm virtual machine, I got message "Disabling IRQ #16" after kernel crashes. Then a network connection card is gone and apparently there is no way how to restore it.

Version-Release number of selected component (if applicable):
kernel-2.6.27-0.337.rc6.git5.fc10.x86_64
kvm-74-3.fc10.x86_64
libvirt-0.4.5-2.fc10.x86_64

How reproducible:
100% (three out of three)

Steps to Reproduce:
1.boot computer into X
2.virsh start tikanga
3.work for a moment in the virtual machine
  
Actual results:
message in /var/log/messages on a host machine and lost network

Expected results:
nothing

Does running the kvm guest with the option -no-kvm-irqchip make any difference?

Comment 4 Matěj Cepl 2008-10-19 22:45:34 UTC
Hasn't happened for some time -- probably fixed somewhere in meantime.
