[Cbe-oss-dev] oprofiled crashing on cell?

[Michael Ellerman]

Hi all,

Running oprofile (0.9.3) on a cell machine (2.6.24-rc7 kernel) I see the
oprofiled intermittently crashing. It only seems to happen when I run an
SPU program.

When it crashes I see this in the log:

oprofiled started Mon Jan  7 18:23:21 2008
kernel pointer size: 8
Read buffer of 98307 entries.
No anon map for pc 0, app anonymous.

Compared to a working run:

oprofiled started Mon Jan  7 18:21:12 2008
kernel pointer size: 8
Read buffer of 11 entries.
Dangling ESCAPE_CODE.
<snip>

I've tried strace'ing oprofiled but that seems to hide the bug. Does
anyone have any ideas?

cheers
