Public bug reported:

Binary package hint: xorg

This happens after a suspend/resume cycle only.  That is, everything
works fine until I suspend and then resume.  On the resume, Xorg crashes
with:

(EE) NVIDIA(0): EVO Push buffer channel allocation failed
(EE) NVIDIA(0):  *** Aborting ***
(EE) NVIDIA(0): Failed to allocate EVO DMA push buffer
(EE) NVIDIA(0):  *** Aborting ***

Backtrace:
0: X(xorg_backtrace+0x3b) [0x8133d6b]
1: X(xf86SigHandler+0x55) [0x80c7d35]
2: [0x52c400]
Saw signal 11.  Server aborting.
Segmentation fault

Trying to start Xorg again yields:
