[gNewSense-users] hibernation (swapping) problem in yeeloong+gNS

[umut ozge]

Dear freedom lovers,

I am running gNS on a 10.1'' Lemote Yeeloong:

uname -a:
Linux umut-yeeloong 2.6.32.11-libre1-lemote #1 PREEMPT Tue Apr 6
09:05:04 UTC 2010 mips64 GNU/Linux

My system seems not to be able to use the allocated swap space.

fstab reads (I set pri to 20000, without this option set it was -1 by default):
/dev/hda5       none            swap    sw,pri=20000    0       0

I have the following in kern.log:
Dec  7 16:29:10 umut-yeeloong kernel: [   16.524000] Adding 2859504k
swap on /dev/hda5.  Priority:20000 extents:1 across:2859504k

and
cat /proc/swaps gives:

Filename                                Type            Size    Used    Priority
/dev/hda5                               partition       2859504 0       20000

Despite all these, there are signs that swaping is not working:

Sign 1: `free' or `top' does not indicate non-zero swap usage even
under thight memory conditions.

Sign 2: When I try to hibernate with

echo disk > /sys/power/state

hibernation cannot succeed and I get the following kernel mesgs,
suggesting that the problem is with swapping (the line just before the
last):

I would apreciate any suggestions on what could be the problem with swapping.
Please bear in mind that I am not a very ``deep'' user of GNU/Linux,
but am eager to learn.

All my best,
