Description of problem: As it says in the summary, the LED for the on-board SATA controllers flashes regularly (about once per second) despite none of the connected devices are mounted. There doesn't seem to be any way to turn that off. Version-Release number of selected component (if applicable): How reproducible: Steps to Reproduce: 1. 2. 3. Actual results: Expected results: Additional info:
Does LED blink also if ledmon is not running? Try this: # kill $(pidof ledmon) # ledctl off={ /dev/sd[a-z] } If LED still blinks it is not caused by ledmon. The LED can blink if hotplugs are disabled for a SATA drive in BIOS (it is disabled by default). Try enabling hotplugs for SATA drives in BIOS. It should help.
Thank you for the info! Running 'ps -xca |grep led' yields no results, and ledctl doesn't seem to be installed. There is no option in the BIOS for hotplugging SATA drives that I am aware of. The mainboard is an MSI 790FX-GD70 and may be too old to have an option for this. I'm still suspecting udev like it was with Debian, yet there is no indication in the process list for anything monitoring SATA devices.
ledctl is a part of ledmon package, so if you don't have ledctl installed, it means that you probably don't have the ledmon package installed. You can check it with: # rpm -qa | grep ledmon If you don't have the ledmon package installed, it isn't a bug of ledmon component. I suppose it can be caused by BIOS SATA settings and/or AHCI driver.
The package ledmon is not installed. The BIOS doesn't make the LED flash by itself.

What might be left that could cause it?
This bug appears to have been reported against 'rawhide' during the Fedora 19 development cycle. Changing version to '19'. (As we did not run this process for some time, it could affect also pre-Fedora 19 development cycle bugs. We are very sorry. It will help us with cleanup during Fedora 19 End Of Life. Thank you.)

I happened to turn off one of the SATA controllers of the mainboard, and since then, the HDD LED doesn't flash anymore. Since there hasn't been anything to find in Fedora that might cause the flashing and since apparently turning off the controller fixed it, indicating that it might be caused by the BIOS as was suspected, I think this bug can be closed.
