Bug Description
Hello,
On my HP Pavilion dv6391 laptop (runs on an AMD Turion64 X2 processor) the systems sometimes crashes when something causes a beep (like if I press backspace on an empty prompt, or search for an invalid package in aptitude, ... ). Before Tribe5 that used to happen a LOT (even in Feisty) ! After Tribe5 it became less frequent.
Notes:
1. Seems that the laptop uses the same speaker for beeping & for audio card, because when I am playing some audio file, and the systems beeps, the audio gets interrupted.
2. I am not using softbeep.
Please find the attached dmesg, uname -a, lspci -vvnn, lsmod & /proc/version_

Hello,
I found a couple of temporary solutions:
1. rmmod pcspkr
2. Another one is without having to remove pcspkr module: In console I can do : setterm -blength 0. There is some other command for xterms. Anyways, that doesn't solve it for GUI applications that may send beeps I think. Anyways, what I meant is, even if I keep pcspkr, but set the terminal not to beep, then when an application run in the terminal send a '\a' it won't cause a crash. I tested that by writing a program that beeps in a continuous loop. The program is attached with this comment.
