Hi,
I found yesterday a problem when booting system on Pentium-M, 32-bit.
I got approximetly this

x86-64: Move vread_tsc into a new file with sensible options
I tested on i386, 32-bit architecture. Both gcc 4.4 and 4.6 result
in same problem. Also -O2 vs -O2 doesn't change anything.
Sometimes bug doesn't appear, or appear differently, for example

Depending on the luck and boot time. All above was registered using qemu.
But I have this (or slightly different - depdnding on boot,
or kernel configuration - messages, just after trace function_graph testing
started) alsoon my laptop.
Reverting commit 44259b1abfaa8bb819d25d41d71e8e33e25dd36a on top of current
kernel make bug disapear.
Disabling CONFIG_FUNCTION_GRAPH_TRACER also make bug dispear.
Bug is preserved at multiple kernel configs.
I send one which is pretty minimized.
Regards,
Witek
