I can reproduce the bug on a 1.6Ghz Via with 2GB of memory. The
partition is on a 4 drive SATA II 7200rpm RAID 5 array. This box is
running at a console level only. I do not have Gnome or any other
applications, even Apache or MySQL installed. When the problem occurs
for me, I have no other applications running.

I can cause this bug with only the barest of processes running,
processor load at 0.00 and 1.9GB of free memory before I begin deleting.
I say this to highlight that I do not believe resources, especially
memory, are the issue.

That said, I now need to contradict myself somewhat.
Due to a different bug, I have had to disable my VIA padlock hardware assisted 
cryptography chip. (i.e. I have blacklisted the padlock_aes and padlock_sha 
modules)
Because of this, all operations on my ext4 data partition (which is encrypted) 
use the processor directly. Therefore during any large operation (e.g. possibly 
during a large delete such as one that causes the problem for me) I would 
imagine that the processor hits 100% usage very quickly. Unfortunately I cannot 
confirm this as the lockup happens too quickly. Therefore, despite the very low 
usage on my box it is still perhaps a processor constraint issue.

Thanks,
David
