Either the sata cable is faulty or its another error. i can disable it with

Code: Select all

sudo dmesg -n 1
but it wont stop the syslog spam. Is there a way to disable it in the syslog also ? i tried the following command but they dont appear to have an effect

Code: Select all

set system syslog global facility protocols level info

Either replace the DVD drive with a new drive, or just remove the defective drive. Either way, the errors should clear up.
I replaced a defective DVD drive last month with a new drive for $13.00.
Good luck.

...you could try coming up with a rsyslog filter to hide such - here's an example here in the forum to give you a basic idea:
viewtopic.php?p=1419860#p1419860
Eg. something among the lines of...
:msg, contains, "exception Emask 0x10 SAct 0x0 SErr 0x4040000 action 0xe frozen" ~

Removing the faulty drive in the first place would probably be better of course (some BIOSes also have the ability to turn them off completely, you might wanna check that as well)...

Have you looked into the BIOS at all? Perhaps it's misconfigured. Unlikely, since it's a laptop though, and laptops typically have lackluster BIOS options, but it's worth a look.

It's almost impossible to fix a mobo controller. Replacing the mobo would work. I have a Lite-ON external USB DVDRW+_ drive just for such occasions, when all else fails (about $15.00 via newegg).
