Hello,
I will format this as a bug report, although I am not sure whether it is
a bug or not.
The problem: closing /dev/dsp seems to freeze my complete system.
Full description:
My system was freezing at some point during shutdown.
Then I discovered it was triggered by killing esd (the sound daemon).
That means if I "killall esd", system freezes.
I then tried "echo hello > /dev/dsp" without esd being started. I hit
Ctrl-C several times. Then the system froze.
Kernel version: Linux version 2.6.0-test11 (root@devmaster) (gcc
version 3.3.3 20031229 (prerelease) (Debian)) #2 SMP Sun Jan 4 17:53:09
CET 2004
Sound card: Intel Corp. 82801BA/BAM AC'97 Audio using i810_audio module
(see system info below for full details)
No oops: Just system frozen.
How to reproduce:
echo hello > /dev/dsp, then kill it.
This will probably not kill your system, but it kills mine reproducibly.
I was too lazy to verify if there have been any changes since 2.6.1, but
there is apparently nothing related to i810_audio between 2.6.0-test11
and 2.6.1.
Any hints? I hope my message is useful.
I am available for anything you may wish me to try. Some more freezes
will not hurt!
Yours sincerely, Antonio Fiol
