Description Jan Kotuc 2005-11-30 21:36:29 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.

Comment 1 Greg Kroah-Hartman 2005-11-30 22:39:19 UTC

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?

Comment 2 Torsten Duwe 2005-12-01 10:12:05 UTC

In most machines, it's actually an "IDE control light"; maybe there's access to another interface, not necessarily with a device attached.

Comment 3 Torsten Duwe 2005-12-01 10:13:20 UTC

hwinfo is still needed, nevertheless.

Comment 4 Jens Axboe 2005-12-01 10:29:30 UTC

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.

This is the output of dmesg | grep ahci ...

May it be helpful to you.

So it is indeed ahci which makes this a dupe of 128597. A SL10 kernel update (when issued) will have the fix for this.
