system crash after waking up from suspend/data loss :(

Topic says it all. After waking the PC out of suspend mode, everything worked fine for about 1 min, then for no reason the system rebooted itself as if one hit the reset switch (non-graceful shutdown). When Arch attempted to boot, it was as though my /etc/rc.conf was corrupted, no keyboard functionality was present and fsck demanded the root password. Once I got around that by booting from the live CD and manually running fsck -v -f on my partitions, I booted into Arch and attempted to log into gdm. The screen just froze, I couldn't hit ctrl+alt+F1 to stop gdm.

Long story short, I restore my backup of /home/myuser and /etc and everything is fine now.

Two questions:

1) Why did I experience data loss? I thought the ext4 delayed write problems were patched since 2.6.30? Guess I need to add the old nodelalloc mount option to my ext4 partitions?

2) How can I disable suspend on my machine to prevent this from happening again?

Thanks!
