Public bug reported:
On my Ubuntu Gutsy 7.10 system (Linux andromeda 2.6.22-14-generic #1 SMP
Sun Oct 14 21:45:15 GMT 2007 x86_64 GNU/Linux) I am sporadically
confronted with the situation that all of a sudden the sound output is
kind of chopped/garbled, i.e. only some fragments of the audio output is
played, some miliseconds are skipped, and so on...
In parallel, some IRQ issues are reported in the dmesg output, which
hint at an IRQ sharing conflict between the {S|P}ATA controller
(ata_piix, pata_marvell via libata) and my sound card (Creative Labs SB
Live! 5.1 using the emu10k driver). Unforunately, I cannot change the
IRQ routing for the PCI card to use an unshared IRQ (most likely a
limitation of the MSI P965 Neo-F V2 mainboard [which is, BTW, running
the most recent BIOS version 3.7] I am using) I will attach detailed
lspci and dmesg output to this ticket shortly.
The problem can only be corrected by a reboot.
Let me know if you need additional details.
