This is a multi-part message in MIME format.
We are using 2.6.22 kernel(for coldfire 5372 processor) , whenever we
mount a memory stick the USB (I am able to access the memory stick
connected to my USB port) and issue "df" command the kernel panics and
the below mentioned message shows up.
The kernel panic occurs frequently even when no operation is performed
for long time.
Can anyone help me on this?
Regards,
Swaroop
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
