I also just triggered a crash using the hang.py script from this forum. I just just switched to ext4 and had to try.
I have two observations someone might find useful.

1) Running as normal user. Ran hang.py and it locked up on the 5th round. I had to push the reset button. Note that the script did not run correctly and I got an error such that "sh: cannot create /proc/sys/vm/drop_caches: Permission denied" at each loop.

2) Running as root user. Ran hang.py and it did NOT lockup. Tried it twice and it completed the full 10 rounds both times. The drop_cache worked as intended in the script.

System is:
Linux version 2.6.28-11-generic (buildd@palmer) (gcc version 4.3.3 (Ubuntu 4.3.3-5ubuntu4) ) #42-Ubuntu SMP Fri Apr 17 01:57:59 UTC 2009 (Ubuntu 2.6.28-11.42-generic)
2GB RAM
150GB 7400 rpm hard drive 75% full
nvidia driver
Converted from ext3 yesterday and ran fine all day doing basic office stuff today.

Let me know if you need any more info. Geoff
