Subject: EeePC 900 reboots/hangs when using using perf -a -f -g

Hi,

On an EeePC 900 running 2.6.36rc3 I've been finding that the laptop
immediately reboots or hangs forever if I run

perf -a -f -g xset dpms force off

. I've got lockdep checking and stack overflow checking on but these
don't make any difference. Using only -a -f doesn't show the problem. I
have also found that disabling eeepc-laptop in the kernel config also
removes the problem.

Any suggestions?
