Bug#594125: [linux-image-2.6.35-trunk-amd64] BSD ring buffer implementation makes suspend to ram unreliable
Package: linux-image-2.6.35-trunk-amd64
Version: 1~experimental.2
Severity: grave
Tags: patch
--- Please enter the report below this line. ---
There is a bug in the linux kernel 2.6.35, that makes suspend to ram
unusable (it seems to be fixed in 2.6.36-rc2) [1]. The symptoms are:
- Suspend to ram from X hangs the computer, the only option is to press
the power button for ~5 sec and thus forcefully turning off the
computer (SysRq does not work for me). After a while (when not
turning off the computer of cause) the fan goes to full power.
- However, suspend to ram from console works.
- The hang does happen every time on my laptop. However, on some
computers that seems to happen only sporadically.
The link [1] contains two possible solutions for this problem.
1. Turn off BSD completely by replacing the corresponding define
in i915_drv.h with
#define HAS_BSD(dev) (0)
2. 2.6.36-rc2 seems to fix the problem (according to a comment on [1]).
