Comment 40 for bug 1167114

If I open GRUB menu before booting sometimes kernel boots successfully (I am writing this on it). Successful dmesg is in attachment.

When I boot default configuration system stalls with blank screen (however crtl+alt+del works).
If I boot "recovery mode" option system stops with last boot messages in text mode.

Boot output screenshots are here

Note that there is some call trace in first three screens.
