SubjectPossible FPU context corruption w/ CONFIG_PREEMPT
Hello, guys.

Heinz-Bernd Eggenstein reports a possible FPU context corruption w/
CONFIG_PREEMPT. Please take a look at the following forum post.

openSUSE 11.3 desktop kernel which has CONFIG_PREEMPT set is
triggering SIGFPE while the default kernel w/o preemption works fine.
He also notes that a similar bug was fixed in 2008 by commit 06c38d5e
(x86-64: fix FPU corruption with signals and preemption) from Suresh.
Does it ring anyone's bell?

Heinz, is there a simple procedure to reproduce the problem, or would
it be possible to lure you into bisection?
