Comment 24 for bug 9713

Not that I know of. You're not booting with 'inotify', are you? I've been
using either an X300 SE or an X850 XT PE (rv370 and r480, respectively), in this
amd64 for quite some time now, and not seen any random hangs. I suspect that
something is up with a kernel driver here: attaching the full output of 'lspci'
might be useful. The fact that it's 64-bit-specific makes me very, very
suspicious of any X issues; almost all of them would also manifest in 32-bit mode.
