A few more info:
- I reproduced the issue on my Lenovo S12 netbook as well, so it's not a
virtual machine-related bug. Here is a poor shot:
http://frugalware.org/~vmiklos/pics/bug/p1040730.jpg
- I'm also attaching the full dmesg in the VM that is finally a text
using serial console.
- On "how to reproduce": sometimes I just get this during boot. If it
does not occur, then it does when using "systemctl emergency".
Please let me know if you need more info.
Thanks,
Miklos
