HElp:: schedule-> switch_to()

[Vikram Mehta]

Hi,
I am worlking on uCdimm
I need some help..

Mtd driver fuction cfi_udelay calls schedule _timeout which calls schedule
which calls switch_to() . this switch_to is a macro in asm-m68k/system.h.

This macro does which some times produces an exception, pr sometimes ends up
dispalying this message
kernel BUG at exit.c:465!
Kernel panic: BUG!
Now this macro works fine in other cases... Y does it not work when called
by mtd driver code?

Please help me on it
