in drivers/serial/atmel_serial.c, add the IRQF_DISABLED flag to request_irq.
When linux is running without adeos, the AT91 serial driver interrupt
is shared with the timer interrupt, so it automatically gets this
flag. Adeos does not use the same hardware timer as linux, so, when
adeos is enabled the serial interrupt is no longer shared with the
timer interrupt and it no longer gets this flag.
