I have the same problem with kernel 3.11.6 on Gentoo Linux (stable) with a
Radeon HD 4650. Hibernation itself works, but shortly after resuming the
machine Xorg crashes with a bus error. Additionally dmesg contains messages
about GPU lockups before or after hibernating. Removing the uvd/smc blobs s=
tops
Xorg from crashing, but disables direct rendering (including XVideo, =E2=80=
=A6). Note
that Xorg does *not* crash after resuming from suspend to RAM.
Downgrading to 3.10 (with the same firmware package) does not solve the
problem, so I=E2=80=99m back to 3.4.67 for now, which works (both hibernate=
/direct
rendering) for me.
