OOPS 2.6.16 and 2.6.16-git14

OOPS 2.6.16 and 2.6.16-git14

[Erik Slagter]

I get a kernel OOPS using 2.6.16 and 2.6.16-git14, I was using 2.6.14.2
before without the problem.

The OOPS happens when doing either

echo "3" > /proc/acpi/sleep

or

echo "mem" > /sys/power/state

As I have a laptop without serial ports, I'd have to write down the
oops, so please forgive that I didn't write down ALL the output, I think
I have the most important stuff, though.

Please note that it also happens when mentioned modules are not linked
in and that I enabled the kernel read-only pages option (although that
doesn't seem to be related).

I am not subscribed, so please CC.

Nowadays, the common solution for this problem is to capture the output 
using a digital camera and posting an URL to the picture (or to submit 
this bug at http://bugzilla.kernel.org/ which is anyways a good idea 
for issues that might be ACPI related and attach the picture there).

Currently I cannot reproduce this, this may have to do with:

 - moved pl2303 adapter from one usb2 hub to another because kernel
barfed about it and that solved the barfing
 - compiled various versions of the kernel so many times, I lost track
of the exact config
 - different usb hub and perifs at home and at work.

As soon as I can reproduce the issue, I'll file a proper bug report
including photographs of the output.

Thanks for your time and effort.
