[posted the same bug under Debian bugs: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=741554] I've been having this problem on CrunchBang 11 "Waldorf" which is based off Debian Wheezy (I think) I've had to restart the PC 4 times because of this. Every time I try to listen to something, at random points it "hiccups" (basically keeps repeating the last few ms of what I was listening, probably what was on the buffer) and the whole OS becomes unresponsive, CPU raises at around 95-100% at which point I can't do anything but turn the PC off. The GUI (TTY7) becomes very unresponsive (for example when I move a window from one place to another, it slowly creeps to the destination. Also TTYs 1-6 are unusuable as they get flooded with this error: [XXXXX.XXXXXX] cmipci: invalid PCM pointer: 0xffff X = random number that keeps increasing. I was mainly listening to music over VLC also tried cmus. On the 3rd and 4th time after restarting I tried I changing the output module from pulse (knowing it can be problematic at times) to alsa but that didn't fix anything. * What led up to the situation? Nothing in particular, this has been happening since I installed the distro. It even behaved this way in the LiveCD session. * What exactly did you do (or not do) that was effective (or ineffective)? I tried to add the unstable repositories in the hope that a more recent version of ALSA might have fixed this bug but it was not the case. * What was the outcome of this action? At first, since it took some time for the error/bug to show up, I thought updating fixed everything, but after 1-2 hours of listening to music the problem resurfaced. * What outcome did you expect instead? Sound to work continiously without this error popping up and rendering my PC completely unusuable. I'm not sure if this is a debian-specific bug as I haven't exited the Debian- sphere, but if this isn't related to Debian itself, please prompt me to send this to ALSA instead. Thank you in advance.
