0005639: mdX_raid1 process produces crashes

After updating the kernel from kernel-2.6.32-220.4.2 to kernel-2.6.32-220.7.1 the system crashes regularly (every 1-2days).<br /> <br /> Two times the system written a crash dump. <br /> I attached the output of a crash bt, sys and log.<br /> <br /> With the old kernel the system runs fine.
