Bug Description
Binary package hint: linux-headers-
OS: Ubuntu 6.06.1 LTS
Hardware: Shuttle SB75G2 motherboard (Intel 875 based)
Audio Hardware: Intel ICH5 - snd_intel8x0
Some time after booting up, my sound stops working. I see the following message in the kernel log:

Sep 22 10:33:50 localhost kernel: [17214565.236000] Disabling IRQ #7
I tried booting with the "irqpoll" option, but that causes other strange behavior (The drive appears confused (ireason = 0x01)).
I then booted with these options: "acpi=debug pci=routeirq apic=debug". dmesg shows:
Bad page state at free_hot_cold_page (in process 'aplay', page c13cff24)
flags:0x80000414 mapping:00000000 mapcount:0 count:0

Trying to fix it up, but a reboot is needed
During a search, I found a message referencing a patch (http://
root@foo:/usr/src# patch --dry-run -p0 -i patches-
missing header for unified diff at line 3 of patch
patching file linux/sound/
Reversed (or previously applied) patch detected! Assume -R? [n]
Apply anyway? [n]
Skipping patch.
2 out of 2 hunks ignored -- saving rejects to file linux/sound/
I'm not sure if this matters, or if I'm looking in the right place, but /proc/interrupts seems to say that irq7 is not being shared:
root@foo:/usr/src# cat /proc/interrupts | grep 7
7: 5355 XT-PIC Intel ICH5
Any help would be appreciated.
Thanks,

Thank you for taking the time to report this bug and helping to make Ubuntu better. You reported this bug a while ago and there hasn't been any activity in it recently. We were wondering is this still an issue for you? Can you try with latest Ubuntu release? Thanks in advance.
