You could be right that all the devices have common firmware (and bug).  It
just feels remote in this case.

More importantly, some interesting research on the Ubuntu bug report by a
number of users:

Ubuntu 9.10 (Karmic) shows the bug with 2.6.28, 2.6.29, 2.6.31, 2.6.32.

Ubuntu 9.04 (Jaunty) shows NO bug with 2.6.28, 2.6.30, 2.6.31, 2.6.32

This has been confirmed by three different users.  Ext4 has been ruled out
(same results with ext2).

Two questions:  Is this a bug outside the kernel space?  And how can a
userspace bug affect the disk operations?
