Title:
MMC/SD memory card reader stops working after hibernate and resume
Status in Linux:
Confirmed
Status in linux package in Ubuntu:
Won't Fix
Bug description:
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:
