Can you please boot the kernel in the minimal configuration (init=/bin/bash)
and try to hibernate, ie.

# mount /proc
# mount /sys
# swapon -a
# echo disk > /sys/power/state

Also, please check if anything changes if you do

# echo shutdown > /sys/power/disk

before the last command above.

Greetings,
Rafael

I just want to add, I built 2.6.23-rc2 on Aug 4th and this happened on Aug 
12 and I suspend once a day. And the only thing which was odd was the 
uptime, nothing else.

I rebooted with 2.6.23-rc3 today, so the odd uptime is gone.
Should I try 8 suspend cycles or something to reproduce it again?

I did, but what could change? I did not see anything, nothing dmesg, no 
odd uptime etc.

Well, if you can, please try to do something like this.

I tried 20 suspend cycles, but this time with 
 echo reboot > /sys/power/disk

Nothing special happend.

I could try with "echo shutdown" if this makes sense, tomorrow.
Just let me know.

Please try "platform" (ie. the default).  "shutdown" is very similar to
"reboot", so I think it'll behave correctly.
