Bug Description
Binary package hint: linux-source-2.6.22
My laptop has a weird DSDT which is not supported out of the box. Under Feisty, I could load a custom DSDT that would enable sound on my laptop. Since my upgrade this morning, I noticed I did not have sound. I checked /var/log/messages and noted the following:
fubar@fry:~$ cat /var/log/messages | grep DSDT
Jun 20 08:49:58 localhost kernel: [ 20.165245] ACPI: Looking for DSDT in initramfs... successfully read 31951 bytes from /DSDT.aml.
Jun 20 08:49:58 localhost kernel: [ 20.165305] ACPI (tbget-0297): Table [DSDT] replaced by host OS [20060707]
Jun 20 11:07:27 localhost kernel: [ 0.000000] ACPI: DSDT 7FE9311A, 8A9C (r1 TOSQCI Denver 6040000 MSFT 3000001)
Jun 20 12:12:45 localhost kernel: [ 0.000000] ACPI: DSDT 7FE9311A, 8A9C (r1 TOSQCI Denver 6040000 MSFT 3000001)
The upgrade occurred around 11am. As you can see, prior to the upgrade the DSDT was loaded correctly, however now it is not loaded. I hope this functionality was not done away with, as I have no other options that I'm aware of to get sound working.
