Using Ubuntu 10.04 with kernel 2.6.32

In KMS mode the system fails to suspend both to ram and to disk. 

The problem persists in single-user mode.

I followed the instructions from
https://wiki.ubuntu.com/DebuggingKernelSuspend

After performing
sudo sh -c "sync; echo 1 > /sys/power/pm_trace; pm-suspend"

The output from dmesg points to
[ 0.333831] hash matches
/build/buildd/linux-2.6.32/drivers/base/power/main.c:433
[ 0.333853] block loop5: hash matches
