Comment 4 for bug 521779

There might be a few kernel command line options you could play with (Note, I have the AOA110 model which should be identical to yours except the hard drive, IIRC). I think I see the bad interrupt message every time a hang or crash happens, so I would see that as a secondary thing.

1. usbcore.autosuspend=1 is the system more stable when you remove this?
2. enable_mtrr_cleanup=1 This resolves a BIOS bug of the Aspire One and could help stability as well as performance. The AA1 has all MTRR registers clobbered by default, leaving no entry for the video RAM. With it you get one.
3. mem=nopentium We had been looking at issues in older kernels. If the issue still occurs playing around with the above two options, then try this one.

Thanks.
