Description of problem:
If I manually launch artsd and then kill it, linux locks up totally. If I log in
at console with KDE and sound turned off in KDE, I have no problems. If sound is
turned on in KDE, KDE and sound works fine until I log out, then at log out
linux instantly locks up. I can achieve the same awful result under GNOME. I
only have had this problem since upgrading to kde and arts 2.2.2.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Log in using Gnome. Username (root or otherwise) isn't important.
2. Launch a terminal window.
3. Run "/usr/bin/artsd &" or "nohup /usr/bin/artsd".
4. Issue a "kill -9" on the artsd process.
1.Log in using KDE.
2.Launch KDE Control Center. Go to Sound, Sound Server. Check "Start aRts sound
server on KDE startup". Go to Sound I/O tab. Select sound I/O method "Open Sound
System." Click on the Apply button. Click on File, Quit.
3.Open a new terminal window.
Actual Results: Linux just freezes up. All networking stops. All daemons seem
to stop working. The keyboard and mouse are unresponsive. If logged in with
GNOME, the image of the GNOME screen freezes. If logged in with KDE, the screen
simply turns black. (I call this the black screen of death, or BSOD :) to misuse
the all-to-familiar phrase).
Expected Results: No lockup. Child processes of the login exit gracefully. All
linux software and attached hardware :) continues to function properly. Console
screen goes back to an X login.
I run RH 7.2 with all updated rpms on updates.redhat.com ftp site (7.2/en/os).
For example, I use kernel-enterprise-2.4.9-21, kdeXXXX-2.2.2-X, and
arts-2.2.2-2; that is, whatever is on updates.redhat.com as of date 2002/02/27.
Sound hardware is built into Intel motherboard 815ee.Since RH 7.0 I have seen
these messages in /var/log/messages:
Feb 27 07:56:04 waves modprobe: modprobe: Can't locate module sound-slot-1
Feb 27 07:56:04 waves modprobe: modprobe: Can't locate module sound-service-1-0
Notwithstanding these error mesages, sound works on my system. For example, when
artsd is running I can play music through xmms under GNOME and KDE (but under
KDE I also have to have OSS configured as my sound server).
It's just that when artsd is killed, my system crashes absolutely and

Good news. RedHat kernel 2.4.9-31 fixes the problem. It was a faulty i810 audio
driver and it is fixed in kernel 2.4.9-31.
