MTD XIP related issue

Wed Nov 12 09:08:28 EST 2008

While porting Linux kernel 2.6.26 on an ARM922T based custom board for
XIP kernel, I came across the following bug report during boot-up:

...

Kernel panic - not syncing: Attempted to kill init!

Although it happens only for few of the bootups, otherwise it displays
