I dug around on the Tumbleweed portal and through the component list in Bugzilla and I couldn't figure out the "appropriate" means to file bugs/quirks like this. Kernel: 3.0.0-39-desktop I had just woken from sleep (`s2ram -f -s`) and hit the following trace in my logs. As it usually happens with issues like this, programs that interact with the kernel started to hang (power settings changes, etc), so I tried to reboot and subsequently had to hard shutdown after the kernel wouldn't properly shut down the network stack. I feel a bit guilty posting stuff like this to the mailing list, give me a Bugzilla component and I'm golden :) Aug 10 09:49:30 kiwi kernel: [160781.642292] kernel BUG at /usr/src/packages/BUILD/kernel-desktop-3.0.0/linux-3.0/drivers/pci/msi.c:315!
