X crashes and suspend fails upon suspend-by-closing-the-lid after 20+ hours of X uptime

Hello all!
After using my laptop reaches more than about 20 hours of uptime (and I have a
couple of suspend/resume cycles in between by closing the lid) the next suspend
fails like this:
The system never sleeps, instead the kernel dmesg stops at:
> PM: Syncing filesystems ... done.
> PM: Preparing system for mem sleep
and never makes it to
> Freezing user space processes ... (elapsed 0.01 seconds) done.
> Freezing remaining freezable tasks ... (elapsed 0.01 seconds) done.
> PM: Entering mem sleep
> ...
Furthermore, if I open the lid I find that X has crashed, my whole session is
lost and I am back at the display manager to login.
The only fix I have found to this problem is either
-> Never suspend by closing the lid, or
-> Always kill the X server every about 10-12 hours
I am using a Lenovo T420 with HD3000 onboard and no nvidia present. There is an
active thread here https://bbs.archlinux.org/viewtopic.php?id=144381, ignore
the title saying about linux 3.4, it happens with kernels back to 3.0
(and probably older)
It happens with
-> xorg-server-1.12.3
-> xorg-server-1.12.3.901
-> xorg-server-1.12.4
after the failed suspend, the end of /var/log/Xorg.0.log is this

Kernel-side (I don't know if this is relevant, but anyway), execution stops at:
> drivers/tty/vt/vt_ioctl.c:133: wait_event_interruptible
> drivers/tty/vt/vt_ioctl.c:1426: vt_waitactive
> kernel/power/console.c:19: vt_move_to_console
> kernel/power/suspend.c:98: pm_prepare_console
> suspend_prepare() called
To make things a bit more weird, if I choose to shutdown or reboot
after a failed suspend, sometime before the end the kernel 'wakes up'
and actually suspends my laptop. On resume, the reboot/shutdown
continues.
If you need more info, please request it, I will make it available.
Thanks and sorry for the long post.
