Drew Woodard (drew-woodard) wrote : snd-hda-intel with flashplugin-nonfree causes browser crash on close

Binary package hint: linux-source-2.6.20

steps to reproduce this bug:
1. use a machine with an onboard sound chipset that loads snd-hda-intel such as the "realtek hd audio" (ALC883)
2. load firefox with flashplugin-nonfree and navigate to a site with flash videos that play audio, almost anything on google video or youtube
3. load a video, let it play for a few seconds, then navigate away from the page while the video is playing, or close the browser tab while the video is still playing. Around 20% of the time firefox will freeze and have to be terminated.

Testing indicates this is a sound-related problem for the following reasons:
several other people with the same problem reported having sound chipsets that use the same drivers.
this problem is not limited to firefox, it can also be reproduced in konqueror.
I was able to stop the freezing by disabling onboard sound in the bios, another user reported stopping the problem by switching to different sound card

the problem has been discussed in the following bug report, with sound-specific discussion starting on 2007-05-10

also one user reported they could avoid the problem by reverting to the pre-feisty kernel 2.6.15-27
