Hi Edwin,
The Realsil/Realtek rts5139 card reader driver polls it's hardware at 20Hz and has racked up 25 minutes of processor time over a few days on this Sandy Bridge media centre box, without any cards inserted. This is more than the sum of all the other processes (including X):
$ ps -ef | grep rts5139 root 691 2 0 Aug03 ? 00:00:36 [rts5139-control] root 693 2 0 Aug03 ? 00:25:36 [rts5139-polling]
The kernel is stock 3.5.0 without debug; would it help if I log a bug report or eg collect further detail?
Thanks, Daniel -- Daniel J Blueman
