Public bug reported:
On a fresh boot, the MMC/SD memory card reader on my laptop works fine.
However, if I hibernate and resume my laptop and attempt to use the
MMC/SD memory again, the laptop fails to read the memory card and I
receive a kernel trace from the driver.
The kernel trace is as follows:
[208991.375755] irq 21: nobody cared (try booting with the "irqpoll" option)
