Well, I've just been hit by the 010G bug, the drive completely disappeared from the boot scan, had to power cycle it to get it back.
Have downgraded it to 000F and all is well again (and the speeds have jumped back up a touch).
That'll teach me for procrastinating on the firmware downgrade.
[edit]FYI: to get a dead Crucial drive back:
1)Switch off, unplug SATA lead to SSD and leave power lead in.
2)Switch on, go into BIOS and leave it alone for 20 minutes.
3)Switch off, unplug power lead for 30 seconds, reconnect only power lead.
4)Switch on, go into BIOS and leave for 20 minutes again.
5)Switch off, reconnect SATA lead.
Now when you switch back on the drive should have recovered and you can flash to a more stable firmware.
