Reason for closing:  Upstream
Additional comments about closing:  OP has not responded but if it is still a problem then this should be reported to the kernel bugtracker assuming it wasn't already.

It seems to be related to the rtsx_usb kernel module. I'll disable it and see if that changes anything.

After disabling the rtsx_usb module and its dependencies (rtsx_usb_sdmmc and rtsx_usb_ms), the problem has vanished. It is indeed a bug in rtsx_usb*.
