Ok, I'm now testing the current patch on my Dell GX270 (Pentium-4, ugh)
system.
Things are not working too well.
Sometimes the system suspends with no problems, but sometimes it seems
to suspend and wake up instantly:

And after the wake up things seem not to work right - doing a "dmesg" on
a serial console hangs for example.
