Bugzilla – Bug 136189
HDD control light
Last modified: 2005-12-05 09:32:05 UTC
From the moment of pressing Enter in Grub to boot the SUSE Linux 10.0 on, the LED that indicates that hard disk is in use is constantly on. I have a Fujitsu-Siemens Amilo PRO V2045 notebook. On windows XP, the LED is only on when hard disk is really in use, and otherwise is off. It's not a real bug, since it doesn't affect the performance, but it's quite annoying. And it has to be in the kernel, since the light is ALWAYS on, i.e. not only when X server or desktop environment or whatever is running.
Are you sure that nothing is accessing the hard disk? can you attach the output of running 'hwinfo' so we can see which ide controller this machine has?
In most machines, it's actually an "IDE control light"; maybe there's access to another interface, not necessarily with a device attached.
hwinfo is still needed, nevertheless.
If you are using the ahci driver for your sata controller, then this bug has already been fixed. # dmesg | grep ahci should tell you if that is the case.

A SL10 kernel update (when issued) will have the fix for this. *** This bug has been marked as a duplicate of 128597 ***
