Comment 20 for bug 74877

I have a similar problem with feisty on an HP TC4200 Tablet PC (see bug #89779). I followed the procedure above (disabling the ata_piix module, applying the ide_acpi and rebuilding the kernel). I can now suspend and resume successfully with the new kernel.

As an aside, I had to apply the patch manually (too many hunks failed). I downloaded the kernel sources this morning, so they should be the latest. I was running 2.6.20-9-generic, but it looks like the kernel sources are 2.6.20-10 (or something; the new package built is called linux-image-2.6.20-ubuntu1.20070306_2.6.20-ubuntu1.20070306-10.00.Custom_i386.deb). This is my first time rebuilding an Ubuntu/Debian kernel, so I'm not sure of the naming convention (although I used --add-revision 20070306 when I built it). In any event, I've attached the patch that applies cleanly to the current sources.
