I used 2.6.21rc6 the last 3 days and got the same issue and no
additional debugging info (just Magic number: 0:692:668 )
Im not sure if i miss any rtc stuff in my kernel, but the
resume-tracing help says it would screw up my clock and this is indeed
happening.
I dont know anything about printk and udelay, maybe i will look for a howto.

Because its a module?
Well, the ipw3945 driver is only available as a module and since the
resume mostly freezes after a few hours of uptime and the issue also
can take days to appear again i would not be able to go online for a
long time.
But if no other choice, i could reboot the laptop with a no-modules
kernel every morning before i go to work, suspend it, and try to
resume when i come back.
This scenerio has a very high probability of a frozen resume (like
50%) while after a fresh boot i can suspend and resume 30 times in a
row without a issue (even with full ram)
