Suspend causes immediate resume
I am using Fedora Core 5 with the standard kernel (2.6.17-1.2185_FC5smp
currently). I am having trouble getting suspend to work. This is a desktop
computer, not a laptop.
When I choose Suspend from the Gnome System menu, my computer powers off,
but then a split second later, before the fans have even stopped spinning,
it powers right back on. This works correctly under Windows XP. Normal
shutdown works correctly, properly powering the system down.
This is what dmesg shows after a suspend:
PM: Preparing system for mem sleep
Freezing cpus ...
Breaking affinity for irq 0
CPU 1 is now offline
SMP alternatives: switching to UP code
