I am using LinuxMint 12 on my Toshiba techra M11 Laptop. I never use bluetooth so I thought it would be a good idea to disable it. I read through a FAQ here and disabled bluetooth in the rc.local file. Here's the link

- Code: Select all
1k. Disable bluetooth on startup
Open rc.local as root:
Code: Select all
gksu gedit /etc/rc.local
Add the line "rfkill block bluetooth" above "exit 0", like so:
Code: Select all
rfkill block bluetooth
exit 0
And everything was fine. A few days later I had a lockup, the mouse was frozen, the clock was frozen.
I shrugged it off but it started happening pretty frequently, every few hours or so. I looked through my system log and found tons of errors from the internal usb bluetooth adapter. Here's a snippet from my syslog. I tweaked any usb settings I found in my BIOS the only one was disable legacy mode. It didn't change a thing.

This kept repeating over and over almost every second, eventually it lead to some sort of hardware lockup. I removed the code from rc.local and it started working fine and the lockups have gone away, but of course, now bluetooth is enabled again.
So my questions are this, why did it keep disabling/re-enabling the bluetooth? And why did this cause a lockup? Finally, are there any other ways to disable bluetooth that won't result in a crash?
Here's my system info, would anything else be helpful?
