pilot-xfer -l can successfully list all the databases on the Visor,
and then the oops occurs on disconnect.
pilot-xfer -b . to try to backup all the databases times out (on
MailDB), and then the oops occurs on disconnect.

although at the moment I can't seem to duplicate that since I can't
get the usb-serial module to load at all anymore under that kernel.
(It complains that it cannot find the kernel version for which the
module was compiled, even after I ran make clean; make; make modules;
make modules_install; reboot with new kernel.)

Yes, see above.

Below find another ksymoops which matches the above dmesg- it looks
like the same bug, but just in case it matters...
ksymoops 2.3.4 on i686 2.4.0-test1. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.0-test1/ (default)
-m /usr/src/linux/System.map (default)
Warning: You did not tell me where to find symbol information. I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol
resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to
find
map, modules, ksyms etc. ksymoops -h explains the options.
