During heavy disk write activity (eg. swapping, writing large files to disk), the system freezes hard (becomes 100% unresponsive) with the CPU fan spun up high, and stays that way until a hard reset.
I've noticed this problem under two separate installs of 12.04 64-bit, on two different SSDs. There seems to be some race condition exposed by the pure speed of the writes?
