>Description:
Sometimes a suspend/resume cycle will result in active processes dying from SIGFPE:

Feb 27 19:16:26 lucy-11i386 kernel: pid 997 (sendmail), uid 0: exited on signal 8
Feb 27 19:16:26 lucy-11i386 kernel: pid 1173 (Xorg), uid 0: exited on signal 8
Feb 27 19:16:26 lucy-11i386 kernel: pid 901 (ntpd), uid 0: exited on signal 8 (core dumped)
Feb 27 19:16:26 lucy-11i386 kernel: pid 1275 (upowerd), uid 0: exited on signal 8 (core dumped)
Feb 27 19:16:26 lucy-11i386 kernel: pid 700 (devd), uid 0: exited on signal 8 (core dumped)

. this results in a very un-useful system.
>How-To-Repeat:
Just suspend/resume a bunch.

 Hi,
 
 After resume, starting any processes would also result in SIGFPE.
 
 This time i was lucky enough to get to a non-X newcons login prompt,
 and login would spawn fine, but the shell(s) would die instantly with
 SIGFPE.
