When Attempting to sync a Handspring Visor (PalmOS USB device), I
sometimes (about 1 time out of 4) get the following panic.

at?

Here you go:
ksymoops 2.4.5 on i686 2.4.21-rc2. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.21-rc2/ (default)
-m /boot/System.map-2.4.21-rc2 (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.
Error (expand_objects): cannot stat(/lib/ext3.o) for ext3
ksymoops: No such file or directory
Error (expand_objects): cannot stat(/lib/jbd.o) for jbd
ksymoops: No such file or directory
Warning (map_ksym_to_module): cannot match loaded module ext3 to a unique module object. Trace may not be reliable.

Does the same thing happen if you use the uhci.o driver instead of the

It definitely appears to be a problem with usb-uhci.
