Comment 4 for bug 539655

<Keybuk> could you attach this "ps" output to the bug
 also I don't suppose you could gdb attach to plymouthd and get a backtrace?
<smb> Keybuk, Hm, not using gdb too often... How would I break to a gdb command line after attaching to the process
<Keybuk> does it not break?
<Keybuk> strace instead of gdb?
<smb> No it just tells me attached to process x and stays there
<smb> I don't think it will show much as it seems to be stuck

<smb> Keybuk, strace seems to lockup too, but maybe /proc/x/wchan = nouveau_gem_ioctl_cpu_fini helps?
