I'm finally through compiling all kernels between the last good and first bad one (slow hardware sucks ;) ) -- the problem was introduced in the patch from 2.6.16-rc5 to 2.6.16-rc6, and is apparently not present in any -mm releases before 2.6.16-rc6.
I'll try to isolate which change between 2.6.16-rc5 and -rc6 causes it... But it would be nice if someone who knows a bit more about the code involved could look at it. l - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
