On the face of it, this looks like it might be a problem in ext3 or the memory management code.Well here is a dmesg extract with usb-storage-debug turned on and the oops and the output of ksymoops. There doesn't appear to be much wrong with usb-storage? I am no expert...

OK here is a newly generated oops and ksymoops output on kernel 2.4.21-pre3-ac1.
This is created by simply copying a large file from the USB hard-drive to a regular disk. It will get so far through copying (a different amount each time) and then cp will segfault and returm to the prompt.
As mentioned before, this all works fine on a USB1.1 port.
Interestingly, I compiled 2.4.21-pre3-ac4 today and tried that and instead of segfaulting, the i/o seems to hang altogether and cp never returns and you CANNOT kill the process or free the USB hard-drive, sync will not complete etc... There are no oopses generated in this case. The only way to free it is to HARD-RESET the machine, init 6 or halt or shutdown all hang.
Anyway. Here it is.

If you suspect the problem really lies in usb-storage, you could try enabling the debug option for usb-storage and recompiling it. Then see what your kernel log has to say.

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.
Warning (compare_ksyms_lsmod): module ext3 is in lsmod but not in ksyms, probably no symbols exported
