Hi Everybody, Been trying to find a solution to this for a while. Using FC2 with a KDE desktop. My sound works fine the first time I log in. Upon subsequent logins, aRTs is running but does not accept sound to play (i.e. the play button is pressed but nothing is happening). If using ALSA to play sound directly (e.g. using XMMS and the ALSA plugin), it is trivial to make the sound skip, where on the first login it was difficult. When I logout, I get this from syslog: Sep 26 15:39:22 Berdoo kernel: irq 11: nobody cared! (screaming interrupt?) Sep 26 15:39:22 Berdoo kernel: irq 11: Please try booting with acpi=off and report a bug Sep 26 15:39:22 Berdoo kernel: Stack pointer is garbage, not printing trace Sep 26 15:39:22 Berdoo kernel: handlers: Sep 26 15:39:22 Berdoo kernel: [<42db33e1>] (snd_audiopci_interrupt+0x0/0x16a [snd_ens1371]) Sep 26 15:39:22 Berdoo kernel: Disabling IRQ #11 I would be infinitely surprised if this was not related :) I did boot with acpi=off (or at least I attempted to. I put acpi=off at the end of the kernel command line in GRUB. That should do it, right?) but the same message came up. I saw a similar bug at https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=126322 that was apparantly fixed with a new kernel. I am running kernel-2.6.8-1.521 updated via yum. The original kernel had the same problem. Any help would be appreciated. Thanks. Paul Kopacz
