usb device problem

[cheng <jinzhcheng@xxxxxxx>]

hi
i has ported s3c2410 udc driver form linux-2.6.7 to 2.4.18 kernel. and i
used "modprobe g_file_storage.o file=/dev/sda1". and connectd usb device
to winxp host.
when i copied big dir(1.2G) from host to device and would failed!(but
copy the file which size was 300M would success)
and device kernel's dmesg had "kernel BUG at buffer.c:509!" information.
i has formated usb device to vfat type. 
I'm wondering what is the reason of this problem?
