Hi Ingo, Steven, everyone,

[ Please CC me in replies ]

I have just tracked down a regression in 2.6.27-rc2 wrt 2.6.26. Commit 
77a2b37d227483fe52aead242652aee406c25bf0 (ftrace: startup tester on dynamic 
tracing.) causes my laptop to fail to resume from S3 (it simply reboots about 
a second after the resume starts and the display never shows anything).

The patch doesn't revert with patch -R (I don't know if there's a cleverer way 
to ask git to revert it), but the problem goes away if I turn off 
CONFIG_DYNAMIC_FTRACE.

The commit and bisect log are attached. Please can you help me to debug this?

Cheers,
Bruce
