Hi all,

I am working on a character driver for FPGA, in which i am using a blocked
read call on workqueue. The read call will be unblocked by the Interrupt
from the Fpga to PPC Cpu.

The problem is that if the process is in blocked mode and then an Interrupt
occurs the system gives kernel Panic where as it get unblocked and start
reading the data but very soon it gets crashed.

Please send me your suggessins regarding the mentioned problem.
Thanks in advance 
with regard
