Possibly a JASSERT?  Pretty slim info to go on.  Stephen will be able to
fix it, I imagine, because everyone knows the major Linux hackers have ESP.

Getting the function name and a few of the details would be a good start.
If you can compile the kernel with KDB (patches included with ext3), then
you can do a stack trace (the "bt" command), to help out a bit more.

Haven't heard much in this regard.  Have you checked bugzilla?  It may be
because of highmem or something.  Because it is basically your whole
installation on a single filesystem, it is also harder to narrow it down
by the type of I/O that is being done.
