Solid State Drive Occasionally Seems to Disappear, Fine After Reboot

Hi everyone.

I'm running Arch 64 on an Acer Timeline 3810T, with an 80 GB SSD and ext4. A few times recently, it's like the drive suddenly disappears, and I'm down to ram. Resources fail to be found, icons turn to crap, and all unopened programs ranging from Firefox to ls are nowhere to be found. I can manage to bring up Gnome's shutdown dialog, but the letters are all boxes, and shutdown hangs after complaining about ext4, among other things. After a hard reboot, things seem ok.

fsck doesn't report any problems. What could this mean? I don't even know if this is a hardware or a software problem. Any help would be greatly appreciated.

SSD: ATA Intel SSDSA2MH080G1GC
fstab:
none                   /dev/pts      devpts defaults 0 0
none                   /dev/shm      tmpfs  defaults 0 0
/dev/sda1              /             ext4   defaults,noatime 0 1
tmpfs                  /tmp          tmpfs  defaults,noatime,mode=1777 0 0

If more information would be helpful, please let me know.

EDIT: My rc.conf includes
MODULES=(acpi_cpufreq cpufreq_ondemand cpufreq_powersave fuse !snd_pcsp !pcspkr)
DAEMONS=(@syslog-ng hal @networkmanager @laptop-mode @avahi-daemon @alsa !openntpd !network !netfs !crond)

I don't know if this has only happened while running powertop, but I do run powertop often. Is it possible that taking this advice:

Suggestion: Enable SATA ALPM link power management via:
echo min_power > /sys/class/scsi_host/host0/link_power_management_policy

might be a problem? I'll stop running powertop altogether for a while and see if the problem persists.

This still happens without running powertop, so that's out. Last time it happened I found reports like this in tty1:

EXT4-fs error (device sda1): ext4_find_entry: reading directory #24588 offset 0

and then:

INIT: Cannot execute "/sbin/agetty"
INIT: Id "c1" respawning too fast: disabled for 5 minutes

What could cause the filesystem to lose everything like this, only to find it again on reboot?

Thanks for any guidance on this issue.

You mention tty1, how about dmesg, anything there?
