Hello all,
We are using uClinux kernel ported for coldfire 5373 processor.
Details of the kernel being used are as follows
Kernel details: Kernel-2.6.22-uc1 with the following patch
1) m532x-core.12.patch
2) m532x-usb.12.patch
3) m5373-core.1.patch
We have connected a USB mass storage device to the board. When large
files are copied to/from the usb device, the kernel panics with the
below message.
Sash command shell (version 1.1.1)

/home/usb> ls
