Hi All, One observation i made during my debug on this problem was, if the FEC
interrupt is disbaled the kernel panic does not occur during file transfer with my USB based flash drive. Not sure what exaclty is the problem bcos FEC uses INTC0 and USB uses INTC1. I enabled FEC and increased USB interrupt level to highest ICR1(0x07) this has reduced the kernel panic problem but i think i need a proper fix for this, can anyone help me on this. I am currently testing the USB Host driver with a small application which writes around 400 files each 30K size (using ext3 filesystem) on an USB flash drive.

Maybe this helps.
