Comment 1 Andrew Morton 2011-07-01 06:47:02 UTC

A regression since 2.6.39, I assume?

Comment 2 Bill Huey 2011-07-01 06:49:52 UTC

Quite possibly yes. I've been getting a lot of random kernel crashes under Ubuntu Natty as well with 2.6.38 so I'm not sure if it's the general state of the kernel or possibly dying hardware.
